Numbers 32:1-5, 33-42

The tribes of Reuben and Gad owned vast numbers of livestock. So when they saw that the lands of Jazer and Gilead were ideally suited for their flocks and herds, they came to Moses, Eleazar the priest, and the other leaders of the community. They said, “Notice the towns of Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sibmah, Nebo, and Beon. The LORD has conquered this whole area for the community of Israel, and it is ideally suited for all our livestock. If we have found favor with you, please let us have this land as our property instead of giving us land across the Jordan River.”

So Moses assigned land to the tribes of Gad, Reuben, and half the tribe of Manasseh son of Joseph. He gave them the territory of King Sihon of the Amorites and the land of King Og of Bashan—the whole land with its cities and surrounding lands. The descendants of Gad built the towns of Dibon, Ataroth, Aroer, Atroth-shophan, Jazer, Jogbehah, Beth-nimrah, and Beth-haran. These were all fortified towns with pens for their flocks. The descendants of Reuben built the towns of Heshbon, Elealeh, Kiriathaim, Nebo, Baal-meon, and Sibmah. They changed the names of some of the towns they conquered and rebuilt. Then the descendants of Makir of the tribe of Manasseh went to Gilead and conquered it, and they drove out the Amorites living there. So Moses gave Gilead to the Makirites, descendants of Manasseh, and they settled there. The people of Jair, another clan of the tribe of Manasseh, captured many of the towns in Gilead and changed the name of that region to the Towns of Jair. Meanwhile, a man named Nobah captured the town of Kenath and its surrounding villages, and he renamed that area Nobah after himself.
