Numbers 32:28-42

²⁸So Moses gave the command regarding them to Eleazar the priest, to Joshua the son of Nun, and to the heads of the fathers’ households of the tribes of the sons of Israel. ²⁹And Moses said to them, “If the sons of Gad and the sons of Reuben, everyone who is armed for battle, cross with you over the Jordan in the presence of the Lord, and the land is subdued before you, then you shall give them the land of Gilead as their property; ³⁰but if they do not cross over with you armed, they shall instead be settled among you in the land of Canaan.” ³¹And the sons of Gad and the sons of Reuben answered, saying, “As the Lord has said to your servants, so we will do. ³²We ourselves will cross over armed in the presence of the Lord into the land of Canaan, and the property of our inheritance shall remain with us across the Jordan.”

³³So Moses gave to them, to the sons of Gad, the sons of Reuben, and to the half-tribe of Joseph’s son Manasseh, the kingdom of Sihon, king of the Amorites and the kingdom of Og, the king of Bashan, the land with its cities with their territories, the cities of the surrounding land. ³⁴And the sons of Gad built Dibon, Ataroth, Aroer, ³⁵Atroth-shophan, Jazer, Jogbehah, ³⁶Beth-nimrah, and Beth-haran as fortified cities, and sheepfolds for sheep. ³⁷The sons of Reuben built Heshbon, Elealeh, Kiriathaim, ³⁸Nebo, and Baal-meon—their names being changed—and Sibmah, and they gave other names to the cities which they built. ³⁹The sons of Machir the son of Manasseh went to Gilead and took it, and dispossessed the Amorites who were in it. ⁴⁰So Moses gave Gilead to Machir the son of Manasseh, and he lived in it. ⁴¹Jair the son of Manasseh went and took its towns, and called them Havvoth-jair. ⁴²Nobah went and took Kenath and its villages, and named it Nobah, after his own name.
