Joshua 22:9-10

9So the Reubenites, the Gadites, and the half-tribe of Manasseh left the Israelites at Shiloh in the land of Canaan to return to their own land of Gilead, which they had acquired according to the command of the LORD through Moses. 10And when they came to Geliloth1 near the Jordan in the land of Canaan, the Reubenites, the Gadites, and the half-tribe of Manasseh built an imposing altar there by the Jordan.
