This introduction to the Book of Joshua (Sefer Yehoshua) establishes its structure as two main parts: the conquest of Canaan and the division of the land among the tribes. Joshua continues Moses’s mission as the universally accepted leader who successfully fulfills the promise of bringing Israel into the land, making this the most triumphant book in Tanakh—one that describes success rather than failure. The Sages taught that if Israel had not sinned, the Bible would contain only the Five Books of Moses and Joshua, since Joshua serves as the authoritative record establishing Israel’s claim to the land and resolving territorial disputes between tribes.
