Joshua 4:12

4:12 The Reubenites, Gadites, and the half-tribe of Manasseh crossed over armed for battle ahead of the Israelites, just as Moses had 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.

Numbers 32:33-42

Land Assignment

32:33 So Moses gave to the Gadites, the Reubenites, and to half the tribe of Manasseh son of Joseph the realm of King Sihon of the Amorites, and the realm of King Og of Bashan, the entire land with its cities and the territory surrounding them. 32:34 The Gadites rebuilt Dibon, Ataroth, Aroer, 32:35 Atroth Shophan, Jazer, Jogbehah, 32:36 Beth Nimrah, and Beth Haran as fortified cities, and constructed pens for their flocks. 32:37 The Reubenites rebuilt Heshbon, Elealeh, Kiriathaim, 32:38 Nebo, Baal Meon (with a change of name), and Sibmah. They renamed the cities they built.

32:39 The descendants of Machir son of Manasseh went to Gilead, took it, and dispossessed the Amorites who were in it. 32:40 So Moses gave Gilead to Machir, son of Manasseh, and he lived there. 32:41 Now Jair son of Manasseh went and captured their small towns and named them Havvoth Jair. 32:42 Then Nobah went and captured Kenath and its villages and called it Nobah after his own name.

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.
