Deuteronomy 3:12-20

“When we took possession of this land, I gave to the tribes of Reuben and Gad the territory beyond Aroer along the Arnon Gorge, plus half of the hill country of Gilead with its towns. Then I gave the rest of Gilead and all of Bashan—Og’s former kingdom—to the half-tribe of Manasseh. (This entire Argob region of Bashan used to be known as the land of the Rephaites. Jair, a leader from the tribe of Manasseh, conquered the whole Argob region in Bashan, all the way to the border of the Geshurites and Maacathites. Jair renamed this region after himself, calling it the Towns of Jair, as it is still known today.) I gave Gilead to the clan of Makir. But I also gave part of Gilead to the tribes of Reuben and Gad. The area I gave them extended from the middle of the Arnon Gorge in the south to the Jabbok River on the Ammonite frontier. They also received the Jordan Valley, all the way from the Sea of Galilee down to the Dead Sea, with the Jordan River serving as the western boundary. To the east were the slopes of Pisgah. “At that time I gave this command to the tribes that would live east of the Jordan: ‘Although the LORD your God has given you this land as your property, all your fighting men must cross the Jordan ahead of your Israelite relatives, armed and ready to assist them. Your wives, children, and numerous livestock, however, may stay behind in the towns I have given you. When the LORD has given security to the rest of the Israelites, as he has to you, and when they occupy the land the LORD your God is giving them across the Jordan River, then you may all return here to the land I have given you.’
