Joshua 22:10-11

10And when they came to the region of the Jordan which is in the land of Canaan, the children of Reuben, the children of Gad, and half the tribe of Manasseh built an altar there by the Jordan—a great, impressive altar.

11Now the children of Israel heard someone say, “Behold, the children of Reuben, the children of Gad, and half the tribe of Manasseh have built an altar on the frontier of the land of Canaan, in the region of the Jordan—on the children of Israel’s side.”
