Joshua 22:10-11

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.

11Then the Israelites received the report: “Behold, the Reubenites, the Gadites, and the half-tribe of Manasseh have built an altar on the border of the land of Canaan, at Geliloth near the Jordan on the Israelite side.”
