Numbers 34:13-15

13Then Moses commanded the Israelites: “This is the land which you will inherit by lot, which the Lord has commanded to be given to the nine and a half tribes,

14because the tribe of the Reubenites by their families, the tribe of the Gadites by their families, and half of the tribe of Manasseh have received their inheritance.

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