Joshua 14:3

And Moses said unto them, If the children of Gad and the children of Reuben will pass with you over Jordan, every man armed to battle, before the LORD, and the land shall be subdued before you; then ye shall give them the land of Gilead for a possession: But if they will not pass over with you armed, they shall have possessions among you in the land of Canaan. And the children of Gad and the children of Reuben answered, saying, As the LORD hath said unto thy servants, so will we do. We will pass over armed before the LORD into the land of Canaan, that the possession of our inheritance on this side Jordan may be ours. And Moses gave unto them, even to the children of Gad, and to the children of Reuben, and unto half the 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, with the cities thereof in the coasts, even the cities of the country round about. And the children of Gad built Dibon, and Ataroth, and Aroer, And Atroth, Shophan, and Jaazer, and Jogbehah, And Bethnimrah, and Bethharan, fenced cities: and folds for sheep. And the children of Reuben built Heshbon, and Elealeh, and Kirjathaim, And Nebo, and Baalmeon, (their names being changed,) and Shibmah: and gave other names unto the cities which they builded. And the children of Machir the son of Manasseh went to Gilead, and took it, and dispossessed the Amorite which was in it. And Moses gave Gilead unto Machir the son of Manasseh; and he dwelt therein. And Jair the son of Manasseh went and took the small towns thereof, and called them Havothjair. And Nobah went and took Kenath, and the villages thereof, and called it Nobah, after his own name.

And this land, which we possessed at that time, from Aroer, which is by the river Arnon, and half mount Gilead, and the cities thereof, gave I unto the Reubenites and to the Gadites. And the rest of Gilead, and all Bashan, being the kingdom of Og, gave I unto the half tribe of Manasseh; all the region of Argob, with all Bashan, which was called the land of giants. Jair the son of Manasseh took all the country of Argob unto the coasts of Geshuri and Maachathi; and called them after his own name, Bashanhavothjair, unto this day. And I gave Gilead unto Machir. And unto the Reubenites and unto the Gadites I gave from Gilead even unto the river Arnon half the valley, and the border even unto the river Jabbok, which is the border of the children of Ammon; The plain also, and Jordan, and the coast thereof, from Chinnereth even unto the sea of the plain, even the salt sea, under Ashdothpisgah eastward.

With whom the Reubenites and the Gadites have received their inheritance, which Moses gave them, beyond Jordan eastward, even as Moses the servant of the LORD gave them;
