Joshua 22:9-10

9So the men of Reuben, Gad, and the half-tribe of Manasseh left the rest of Israel at Shiloh in the land of Canaan. They started the journey back to their own land of Gilead, the territory that belonged to them according to the Lord’s command through Moses.

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.
