📋 Shiur Overview
Summary of the Shiur: Hilkhot Yesodei HaTorah, Chapter 8
Structure of the Chapter – Introduction
The previous chapter (7) dealt with the topic of how a prophet (navi) functions, and at the end there was the commandment (mitzvah) to obey a prophet when he brings a sign and wonder (os u’mofes). Chapter 8 doesn’t really contain new halakhot, but rather is an elaboration of an important detail in the law of believing in a prophet: even with a wonder, if the prophet says something contrary to the prophecy of Moshe, we do not believe him. In order to understand this, the Rambam must first explain the fact that our faith (emunah) in the prophecy of Moshe is fundamentally different from faith in an ordinary prophet.
Novel point in the structure: In Chapter 7, the Rambam explained the substantive difference between the prophecy of Moshe and other prophets (how Moshe’s prophecy was constituted). Here in Chapter 8, he goes on to explain the difference for us – how we believe in an ordinary prophet as opposed to how we believe in Moshe Rabbeinu, which is on a different level.
[Note:] The Rambam did not include the commandment of lo tosifu v’lo tigre’u (not to add or subtract commandments) in Hilkhot Yesodei HaTorah, even though it could have fit very well into this chapter.

Halakhah 1 – The Faith in Moshe Rabbeinu Is Not Based on Signs
The Rambam’s Words:
“Moshe Rabbeinu – Israel did not believe in him because of the signs he performed, for one who believes based on signs has a deficiency (dofi) in his heart, since it is possible that the sign was performed through trickery (lat) and sorcery (kishuf).”
Plain Meaning:
The foundation of faith in Moshe Rabbeinu is not the signs and wonders, in contrast to an ordinary prophet whom we believe through a sign and wonder combined with his worthiness. One who believes based on signs has in his heart a “dofi” – a doubt, because perhaps the sign was produced through sorcery or a trick.
Novel Points and Explanations:
1) A question on the Rambam – the signs in Parshat Shemot:
In Parshat Shemot, God gave Moshe signs (the staff turns into a snake, etc.) so that the Jews would believe him. How can the Rambam say that Israel did not believe in Moshe because of signs?
Answer: When the Rambam says “Israel believed in him” he means the legal obligation (din) of faith that began at the Giving of the Torah (Matan Torah), not the belief that he was an emissary to take the Jews out of Egypt. In Egypt there was not yet any legal obligation to believe – it was before Matan Torah. The signs in Egypt served as a practical mission, not as a foundation for faith in the prophecy of Moshe. (The Rishonim already debated the Rambam extensively on this point.)
2) Explanation of the word “lat” (b’lat):
“Lat” is connected to “b’lahateihem” which appears in the Torah regarding sorcery. “Lat” means quiet/hidden – a trick that one doesn’t see. Earlier in Chapter 7, the Rambam only said “devarim b’go” (something is behind it), and here he specifies: it could be sorcery or trickery (lat).
3) Faith through signs is like testimony – not one hundred percent:
Even when Jews do believe based on a sign and wonder, it is not a one-hundred-percent truth for them. They do it because the Torah obligates them – just as we believe two witnesses even though we know that witnesses can lie. This is the law of testimony (edut): we know it could be otherwise, but the Torah commanded us to accept it this way.
[Digression – analogy to life:] Our entire lives we do things not based on one hundred percent certainty. When a person marries off a child, he is not one hundred percent sure that this is the right match (shiddukh) – one goes with the way of the world, it makes sense, it looks right. That’s how ordinary faith in a prophet works. But faith in Moshe Rabbeinu is much more than that.

Halakhah 1 (continued) – Why Then Did Moshe Rabbeinu Perform Signs?
The Rambam’s Words:
“And all the signs that Moshe performed in the wilderness, he performed them according to the need, not to bring proof of his prophecy.” – All the signs that Moshe performed in the wilderness he did according to the need, not to bring proofs of his prophecy.
Plain Meaning:
Moshe’s wonders served practical purposes – he was the leader of the Jewish people (Klal Yisrael) and took care of their needs.
Novel Points and Explanations:
1) Why does the Rambam say “in the wilderness” and not “in Egypt”?
The Rambam first counts the signs in the wilderness, not in Egypt. Egypt had a different reason: to break Pharaoh, to create a sanctification of God’s Name (kiddush Hashem). But shortly afterward he includes Egypt as well.
2) Examples of “according to the need”:
– The splitting of the Sea of Reeds (Kriat Yam Suf) – “the need to drown the Egyptians” – the Egyptians needed to be drowned, to end the long saga of Egypt.
– Water from the rock (mayim mi’sela) – “he brought down water from the rock” – the Jews were thirsty, water was needed.
– Korach – “the earth swallowed them” – Moshe needed to remove the problem of Korach, to exact punishment.
3) An interesting contradiction regarding Korach:
The Rambam in the introduction specifically brings a proof for Moshe’s prophecy from the verse in Parshat Korach. But here in the halakhot he says that “the earth swallowed them” was only a practical need – to punish Korach – not to prove the prophecy of Moshe. The verses don’t entirely align with this passage.
4) The Ten Plagues – also according to the need:
“And similarly all the other signs” – all other signs, including the Ten Plagues, were for a specific need: “So that you may tell in the ears of your son and your son’s son” – to demonstrate God’s providence (hashgachah) for the Jews, to create a kiddush Hashem. Not in order to prove to the Jews that Moshe Rabbeinu’s prophecy is true.
5) The Rambam is arguing against another approach:
One can hear another approach: that all the miracles and wonders of Egypt and the wilderness were a “build-up,” a preparation for the Revelation at Sinai (Ma’amad Har Sinai) – that Moshe performs so many wonders in front of all the Jews so that they would later believe him at the Revelation at Sinai. The Rambam does not say this. According to the Rambam, all these signs were because that’s what was needed at the time – each wonder on its own had a practical reason.
—
Halakhah 1 (continued) – On What Basis Did They Believe in Him? The Revelation at Sinai
The Rambam’s Words:
“And on what basis did they believe in him? At the Revelation at Sinai, where our eyes saw and not a stranger’s, and our ears heard and not another’s – the fire and the sounds and the torches, and he approached the thick cloud, and the Voice spoke to him and we heard: ‘Moshe, Moshe, go tell them such and such.'”
Plain Meaning:
The faith in Moshe Rabbeinu is based on the Revelation at Sinai, where all the Jews saw with their own eyes and heard with their own ears – not through an emissary, not through someone else.
Novel Points and Explanations:
1) The main emphasis – “our eyes and not a stranger’s, our ears and not another’s”:
The main point is not precisely what they saw (fire, sounds, torches), but rather that they saw it themselves. This is the fundamental difference: with an ordinary prophet we are passive listeners – we have nothing to do with the prophecy itself, we merely accept it. At the Revelation at Sinai, the Jews were a certain kind of partner – they themselves participated in the event. When one has seen something oneself, one doesn’t need to believe anyone – it is not a presumption (chazakah), not testimony (edut), but personal knowledge (yedi’ah).
2) What did the Jews hear? – “And the Voice spoke to him and we heard”:
The Rambam does not say that the Jews heard from God Himself directly. He says that they heard how God spoke to Moshe Rabbeinu: “Moshe, Moshe, go tell them such and such.” This means: the Jews heard with their own ears that God was sending Moshe as an emissary.
3) Dispute with the Zohar:
The Zohar states that the Jews themselves heard “Anokhi” (the first of the Ten Commandments directly from God). The Rambam’s position here appears to be different – he emphasizes that what they heard was how God spoke to Moshe, not directly to them. (This is “another topic altogether.”)
4) The verse “Face to face God spoke with you”:
The Rambam brings the verse “Face to face (panim b’fanim) God spoke with you” as proof. In Chapter 7, the Rambam interpreted “face to face” (panim el panim) as a characteristic of Moshe’s prophecy – “according to the capacity of the emissary.” Does the verse here mean that all the Jews had for a moment something similar to the prophecy of Moshe? No – that is not stated. What “face to face” conveys here is the “not through an intermediary” aspect – that it was a direct encounter, not through a middleman.

Laws of Foundations of the Torah, Chapter 8: The Prophecy of Moshe Rabbeinu — The Foundation of Faith
—
Introduction: The Structure of the Chapter and Its Connection to Chapter 7
Yes, we are learning Laws of Foundations of the Torah, Chapter 8. Continuing about a prophet (navi), a specific topic about a prophet — the prophecy of Moshe.
In an interesting way, as we have learned, the Rambam has a method of beginning with a fact, and afterward he states the commandment (mitzvah). The entire previous chapter was the fact of how a prophet works, and at the end was the one mitzvah of obeying a prophet when he brings a sign. The law is: when he brings a wonder (mofes), then one obeys him.
Now there is going to be another entire chapter, and if I look here, there are no facts in a certain sense — meaning, there are no actual laws (halakhos) in it. But one can say that it is an elaboration of another detail in the law of believing in a prophet when he brings a sign and wonder (os u’mofes).
**[Novel Insight]** The Chapter as an Elaboration of the Law
That is to say, let me explain: the law is that when a prophet comes and brings a wonder, one must believe him. But the Rambam is going to say that here in these laws there are details. One of the important details is that even with a wonder, if the prophet says something against the prophecy of Moshe, we do not believe him.
Now, generally, why? We’ll see. But generally, in order to explain the law, the Rambam explains the fact that it is already established in the prophecy of Moshe. And he also goes on to explain a fact about how we believe in the prophecy of Moshe, what our relationship is to the prophecy of Moshe. After one understands the fact, one will simply understand why when someone who performs wonders comes against the prophecy of Moshe, we do not believe him. This is my novel insight.
The Distinction Between Chapter 7 and Chapter 8
In the previous chapter, the Rambam explained the straightforward distinction between the prophecy of Moshe and other prophets. Here he is going to tell us the distinction for us — how we believe an ordinary prophet, and why we believe differently in Moshe Rabbeinu, on a different level.
Note: “Lo Sosifu v’Lo Sigre’u” (You Shall Not Add and You Shall Not Subtract)
What I find a bit interesting: the Rambam did not hold that the mitzvah of “lo sosifu v’lo sigre’u” — which according to the Rambam means adding or removing mitzvos — is not placed in Laws of Foundations of the Torah. It could very well have been included in this chapter.
True, that’s one way. But in another way, one can say that what was stated at the end of the previous chapter — that when one believes an ordinary prophet, it is only based on the legal principle of presumption through testimony (b’din chazakah b’edus) — is not correct for the prophecy of Moshe. And for that very reason, the prophecy of Moshe is stronger than other prophets, because it is not a presumption. Since it is a clearer matter, there should have been a topic, it should have begun.

Halakhah 1: Moshe Rabbeinu — “They Did Not Believe in Him Because of the Signs”
The Foundation: Faith in Moshe Is Not Based on Signs
The Rambam says: “Moshe Rabbeinu — Israel did not believe in him because of the signs he performed.”
The Rambam has just finished explaining that an ordinary prophet — we believe him for two reasons: we believe because we know he is a righteous person (tzaddik), and therefore he is one who is fitting for prophecy — he doesn’t say fabricated things, he is wise, and all the things he lists that a prophet must be, he is fitting to be a prophet. And after he performs a sign and wonder, the Torah gives us the obligation to believe — that since he is fitting for prophecy and there was a sign and wonder, it becomes like testimony, and therefore we should accept his prophecy.
Moshe Rabbeinu — the Jews did not believe in him because of the signs he performed.
**[Question]** The Signs in Parshas Shemos
It is indeed a good question: the whole thing begins with Moshe! The concept that the Almighty gives a sign and wonder so that the Jews should believe — He took it from Parshas Shemos. You ask a good question, but the Rambam is going to answer it. I just want to explain the question.
**[Answer]** “Israel Believed in Him” — Refers to the Giving of the Torah (Matan Torah)
Apparently, when he speaks here of “Israel believed in him,” he means it began at the Giving of the Torah (matan Torah), not “believed” that he was an emissary to take the Jews out of Egypt. That — being an emissary to take the Jews out of Egypt — certainly yes, was because of the signs that the Almighty gave him. But he is speaking about when there is a legal obligation. There was no legal obligation for the Jews to believe while in Egypt, because it was still before the Giving of the Torah. The Jews did not believe in Moshe regarding any specific legal obligation.
That is what you mean — a bit of a question on the Rambam. There were already early authorities (Rishonim) who argued very strongly against the Rambam regarding these types of proofs.
—
“One Who Believes Based on Signs Has a Deficiency in His Heart” — The Weakness of Faith Through Signs
But the Rambam himself addressed it. In the next section he goes on to say: what about the wonders that Moshe did perform? Why?
“One who believes based on signs has a deficiency in his heart” — someone who believes based on signs and wonders, in his heart it gnaws at him: is it true or not?
Why? Because the Rambam explains: sometimes there is some reason, something “behind the scenes.” You do see some wonder, but when a person unfortunately believes in a wonder, he thinks the whole time: maybe I’m not so smart, maybe it’s a trick, some kind of optical illusion (achizas einayim).
The Rambam says: “Perhaps the sign was performed through ‘lat’ and sorcery.” It says here “lat.” I don’t know — “b’lahateihem” it says in the Torah regarding sorcery — does it mean the same word? I think “lat” means quietly, some kind of… It’s interesting, earlier it just said “things going on behind the scenes” (devarim b’go), and here he specifies: it could be sorcery or “lat.”
Well, when a person does a trick, he has someone under the curtains. You don’t see? He tells him something quietly over there. There is some trick underneath it.
Faith Through Signs — Like Testimony, Not One Hundred Percent
Even when Jews do believe based on a sign and wonder — they believe, as the Rambam said — when they believe it, it is also not for them a one hundred percent truth. They do it because the Torah obligates them. There remains some inclination without that certainty…
Just as when two witnesses come and we know — it could be the witnesses are lying, there are many people who lie — but the Torah commanded us to believe this way, so we believe.
Our entire lives we don’t do things based on one hundred percent. When a person marries off a child, he is not one hundred percent sure this is the right match (shidduch), but he is happy because one goes with the way of the world — so when it makes a lot of sense, it looks that way, perhaps there are better chances, so one goes with it. That is how ordinary faith in a prophet works.
But the faith in Moshe Rabbeinu — the Jews believed much more than that.
—
Why Did Moshe Rabbeinu Perform Signs?
Shortly he will say why the Jews did believe in Moshe. But he pauses here for a moment: but if so, what is the meaning of all those signs and wonders? The first few parshiyos when the encounters with Moshe Rabbeinu — we see that there is a lot with signs and wonders. A person might think that this is the foundation of Moshe, that this is why we believe in Moshe — because of the Ten Plagues and all those things.
“He Performed Them According to the Need, Not to Bring Proof of Prophecy”
Rather, that was not what was important. So what then — why did Moshe Rabbeinu perform so many wonders?
“And all the signs that Moshe performed in the wilderness, he performed them according to the need” — all the signs that Moshe Rabbeinu performed in the wilderness… Interestingly, he does not count the signs and wonders in Egypt — and Egypt had a different reason: to break Pharaoh, to make a sanctification of God’s Name (kiddush Hashem). Why does he say “in the wilderness”? The signs that Moshe Rabbeinu performed in the wilderness, he performed them according to the need — he did them according to the need, whatever the particular need was. “Not to bring proof of the prophecy” — the reason Moshe Rabbeinu did it was not to bring proofs about the prophet, but to do what he does as the leader of the Jewish people (Klal Yisrael). Moshe Rabbeinu, besides being a prophet, is also the leader, and he takes care of the Jewish needs.
Examples of “According to the Need”
So therefore:
– The need to drown the Egyptians — it was necessary to drown the Egyptians in the sea, to end the long saga of Egypt — the Splitting of the Sea (Kriyas Yam Suf), and He saved them through it, and he caused the miracle, the wonder, that the Egyptians should be drowned there.
– He brought down the manna (man) for us — we Jews needed sustenance.
– He split the rock for them — they were thirsty.
– The congregation of Korach rebelled against him — the earth swallowed them — he simply needed to take vengeance, he needed to remove the problem of Korach.
“And similarly all the other signs” — all other signs were also for a particular need.
**[Note]** Contradiction Regarding Korach
It is very interesting. The Rambam — I recall that the Rambam in the introduction brings the proof of Moshe’s prophecy from the verse in Parshas Korach. You see that the earth swallowing them — the Rambam did not bring it as a proof. That was only, as you say, for Korach to be swallowed by the earth, but not in order to prove. The verses don’t entirely align with this section.
The Ten Plagues — Also According to the Need
For example, all the Ten Plagues were simply for the need, as it says so many times: “So that you shall tell in the ears of your son and your grandson” — to show God’s providence (hashgachas Hashem) for Jews, to make a sanctification of God’s Name. Not in order to prove to Jews that Moshe Rabbeinu’s prophecy is true.
**[Novel Insight]** The Rambam Against the Approach of a “Build-Up” to the Revelation at Sinai
Apparently, the Rambam disagrees with another approach. Another approach would have been — I can hear it this way — that all the things are a preparation for the Revelation at Sinai (ma’amad Har Sinai). That Moshe Rabbeinu is a build-up: that he performs so many miracles and wonders in front of all the Jews, so that the Jews should see, and later they should believe him at the Revelation at Sinai.
That approach — perhaps there are others who say so — but the Rambam does not say so. All those signs were because they were needed at that time.
—
Halakhah 2: What Did They Believe Him For? — The Revelation at Sinai
“Our Eyes Saw and Not a Stranger’s, Our Ears Heard and Not Another’s”
And if so, what did they believe him for? What was indeed the reason why Jews believed in Moshe Rabbeinu? Basically, why do we believe in Moshe Rabbeinu?
Yes, if a non-Jew asks you: why do you believe in Moshe Rabbeinu? You wouldn’t have told him because Moshe split the sea? He split the sea because they needed to cross through. Why should you believe in him for another reason?
Perhaps the question means not just “what did they believe him for” at the Revelation at Sinai — when did one need to, or why? Because there was the Revelation at Sinai.
What Was the Revelation at Sinai?
The Rambam says as follows: the Revelation at Sinai was a time when all Jews saw — “that our eyes saw and not a stranger’s” — our own eyes saw, not a stranger, not a prophet told us. “And our ears heard and not another’s” — our own ears heard, not someone else told us.
**[Novel Insight]** The Main Emphasis — “Saw It Ourselves”
I want to stop for a second here. It is correct that he is going to say what was seen, but I feel that the main emphasis one must make here is on this: what exactly was seen — the Rambam is going to lay out what was seen, but one can perhaps even read in a different interpretation of what was seen or what was understood.
The main emphasis here is that this is not like what Rashi says — “I am not testifying to you through words, nor through an emissary” — not that someone told us and we must believe that since he performed a wonder it must be so. We saw it ourselves.
When one saw it oneself, there is no… Usually when a prophet says something, we have nothing to do with the prophecy — we are only receiving, we are the passive listeners. Here there is something — the Jews were in this something of a certain kind of partner, the Jews took something, participated in that event. Whatever it is — what we believe about the Revelation at Sinai are things that we saw ourselves. One doesn’t need to believe anyone for this.
What Did We See and Hear?
The Rambam says: what did we see? “The fire and the sounds and the torches, and he approached the thick cloud, and the Voice spoke to him and we heard.”
What did we hear? The Voice speaks to Moshe Rabbeinu and we hear, because the Voice says to him: “Moshe, Moshe, go tell them such and such.” They heard the Voice as the Almighty speaks to Moshe Rabbeinu.
**[Note]** The Rambam Does Not Say That Jews Heard Directly from the Almighty
He does not say here that the Jews heard from the Almighty Himself — he says that they heard how the Almighty tells Moshe: “Go tell them such and such.”
Discussion: The Zohar Versus the Rambam
It’s remarkable — in the Zohar it says that they heard the “Anochi” (I am). Yes, but that is another topic. What we are saying here is… but that I say, the details are already how the Rambam depicts exactly what was heard — I don’t know if it is essential. I think the main essential point here is that the Jews heard, “our eyes saw and not a stranger’s.”
The Verse “Face to Face God Spoke with You”
He should bring the verse: “Face to face God spoke with you” — in front of you…
Discussion: What Does “Face to Face” Mean Here?
No — “face to face,” I recall that the Rambam interpreted a minute ago regarding the prophecy of Moshe, and one says “face to face” (panim el panim). Face to face — he interprets there — face to face means according to the capacity of the emissary.
Face to face — to say that all Jews for a moment had something similar to the prophecy of Moshe? That is not stated. That is what you yourself are now reading into it.
“Face to face” is a characteristic of the prophecy of Moshe. Yes, but what does it yield there? It doesn’t yield much regarding the prophecy of Moshe. What it does yield is the “not through an emissary” point.
