Numbers 32:1-5, 33-42

Now the people of Reuben and the people of Gad had a very great number of livestock. And they saw the land of Jazer and the land of Gilead, and behold, the place was a place for livestock. So the people of Gad and the people of Reuben came and said to Moses and to Eleazar the priest and to the chiefs of the congregation, “Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo, and Beon, the land that the LORD struck down before the congregation of Israel, is a land for livestock, and your servants have livestock.” And they said, “If we have found favor in your sight, let this land be given to your servants for a possession. Do not take us across the Jordan.”

And Moses gave to them, to the people of Gad and to the people of Reuben and to the half-tribe of Manasseh the son of Joseph, the kingdom of Sihon king of the Amorites and the kingdom of Og king of Bashan, the land and its cities with their territories, the cities of the land throughout the country. And the people of Gad built Dibon, Ataroth, Aroer, Atroth-shophan, Jazer, Jogbehah, Beth-nimrah and Beth-haran, fortified cities, and folds for sheep. And the people of Reuben built Heshbon, Elealeh, Kiriathaim, Nebo, and Baal-meon (their names were changed), and Sibmah. And they gave other names to the cities that they built. And the sons of Machir the son of Manasseh went to Gilead and captured it, and dispossessed the Amorites who were in it. And Moses gave Gilead to Machir the son of Manasseh, and he settled in it. And Jair the son of Manasseh went and captured their villages, and called them Havvoth-jair. And Nobah went and captured Kenath and its villages, and called it Nobah, after his own name.
