Joshua 22:9-10

9So the tribes of Reuben, Gad and half the tribe of Manasseh left the other Israelites in Shiloh, in the land of Canaan. They returned to their own land in Gilead. Moses had given this land to them, as the Lord had told him.

10The 2½ tribes came to Geliloth, near the Jordan River, in Canaan. They built a big altar there, beside the river.
