Joshua 22:10-11

10But while they were still in Canaan, and when they came to a place called Geliloth near the Jordan River, the men of Reuben, Gad, and the half-tribe of Manasseh stopped to build a large and imposing altar.

11The rest of Israel heard that the people of Reuben, Gad, and the half-tribe of Manasseh had built an altar at Geliloth at the edge of the land of Canaan, on the west side of the Jordan River.
