Numbers 32:1-5, 33-42

The people of Reuben and Gad had large flocks and herds. When they saw that the lands of Jazer and Gilead were good for the animals, they came to Moses, Eleazar the priest, and the leaders of the people. They said, “We, your servants, have flocks and herds. The LORD has captured for the Israelites a land that is good for animals—the land around Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo, and Beon. If it pleases you, we would like this land to be given to us. Don’t make us cross the Jordan River.”

So Moses gave that land to the tribes of Gad, Reuben, and East Manasseh. (Manasseh was Joseph’s son.) That land had been the kingdom of Sihon, king of the Amorites, and the kingdom of Og, king of Bashan, as well as all the cities and the land around them. The Gadites rebuilt the cities of Dibon, Ataroth, Aroer, Atroth Shophan, Jazer, Jogbehah, Beth Nimrah, and Beth Haran. These were strong, walled cities. And they built sheep pens. The Reubenites rebuilt Heshbon, Elealeh, Kiriathaim, Nebo, Baal Meon, and Sibmah. They renamed Nebo and Baal Meon when they rebuilt them. The descendants of Makir son of Manasseh went and captured Gilead and forced out the Amorites who were there. So Moses gave Gilead to the family of Makir son of Manasseh, and they settled there. Jair son of Manasseh went out and captured the small towns there, and he called them the Towns of Jair. Nobah went and captured Kenath and the small towns around it; then he named it Nobah after himself.
