Joshua 22:10–14
And when they came to Geliloth 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. / Then 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.” / And when they heard this, the whole congregation of Israel assembled at Shiloh to go to war against them.
