Numbers 34:14-15

14For the tribe of the children of Reuben according to the house of their fathers, and the tribe of the children of Gad according to the house of their fathers, have received their inheritance; and the half-tribe of Manasseh has received its inheritance.

15The two tribes and the half-tribe have received their inheritance on this side of the Jordan, across from Jericho eastward, toward the sunrise.”
