Numbers 32:1

The Petition of the Reubenites and Gadites

32:1 Now the Reubenites and the Gadites possessed a very large number of cattle. When they saw that the lands of Jazer and Gilead were ideal for cattle,

Deuteronomy 3:12-17

Distribution of the Transjordanian Allotments

3:12 This is the land we brought under our control at that time: The territory extending from Aroer by the Wadi Arnon and half the Gilead hill country with its cities I gave to the Reubenites and Gadites. 3:13 The rest of Gilead and all of Bashan, the kingdom of Og, I gave to half the tribe of Manasseh. (All the region of Argob, that is, all Bashan, is called the land of Rephaim. 3:14 Jair, son of Manasseh, took all the Argob region as far as the border with the Geshurites and Maacathites (namely Bashan) and called it by his name, Havvoth-Jair, which it retains to this very day.) 3:15 I gave Gilead to Machir. 3:16 To the Reubenites and Gadites I allocated the territory extending from Gilead as far as Wadi Arnon (the exact middle of the wadi was a boundary) all the way to the Wadi Jabbok, the Ammonite border. 3:17 The Arabah and the Jordan River were also a border, from the sea of Chinnereth to the sea of the Arabah (that is, the Salt Sea), beneath the watershed of Pisgah to the east.

Joshua 13:8-14

Tribal Lands East of the Jordan

13:8 The other half of Manasseh, Reuben, and Gad received their allotted tribal lands beyond the Jordan, just as Moses, the Lord’s servant, had assigned them. 13:9 Their territory started from Aroer (on the edge of the Arnon Valley), included the city in the middle of the valley, the whole plain of Medeba as far as Dibon, 13:10 and all the cities of King Sihon of the Amorites who ruled in Heshbon, and ended at the Ammonite border. 13:11 Their territory also included Gilead, Geshurite and Maacathite territory, all Mount Hermon, and all Bashan to Salecah – 13:12 the whole kingdom of Og in Bashan, who ruled in Ashtaroth and Edrei. (He was one of the few remaining Rephaites.) Moses defeated them and took their lands. 13:13 But the Israelites did not conquer the Geshurites and Maacathites; Geshur and Maacah live among Israel to this very day. 13:14 However, Moses did not assign land as an inheritance to the Levites; their inheritance is the sacrificial offerings made to the Lord God of Israel, as he instructed them.

Joshua 22:4

22:4 Now the Lord your God has made your fellow Israelites secure, just as he promised them. So now you may turn around and go to your homes in your own land which Moses the Lord’s servant assigned to you east of the Jordan.
