Numbers 32:31-36
English Standard Version
Chapter 32
31And the people of Gad and the people of Reuben answered, "What the Lord has said to your servants, we will do. 32We will pass over armed before the Lord into the land of Canaan, and the possession of our inheritance shall remain with us beyond the Jordan."
33And 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.
34And the people of Gad built Dibon, Ataroth, Aroer,
35Atroth-shophan, Jazer, Jogbehah,
36Beth-nimrah and Beth-haran, fortified cities, and folds for sheep.
