Numbers 32:35

We 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.”

Moses gave to them, even to the children of Gad, and to the children 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, according to its cities and borders, even the cities of the surrounding land.

The children of Gad built Dibon, Ataroth, Aroer,

Beth Nimrah, and Beth Haran: fortified cities and folds for sheep.

The children of Reuben built Heshbon, Elealeh, Kiriathaim,

Nebo, and Baal Meon, (their names being changed), and Sibmah. They gave other names to the cities which they built.
