Numbers 34:13-15

13So Moses commanded the Israelites, “This is the land you are to receive by lot as an inheritance, which the Lord commanded to be given to the nine and a half tribes.

14For the tribe of Reuben’s descendants and the tribe of Gad’s descendants have received their inheritance according to their ancestral families, and half the tribe of Manasseh has received its inheritance.

15The two and a half tribes have received their inheritance across the Jordan east of Jericho, toward the sunrise.”
