Joshua 22:9-16
English Standard Version
10And when they came to the region of the Jordan that is in the land of Canaan, the people of Reuben and the people of Gad and the half-tribe of Manasseh built there an altar by the Jordan, an altar of imposing size.
11And the people of Israel heard it said, "Behold, the people of Reuben and the people of Gad and the half-tribe of Manasseh have built the altar at the frontier of the land of Canaan, in the region about the Jordan, on the side that belongs to the people of Israel."
12And when the people of Israel heard of it, the whole assembly of the people of Israel gathered at Shiloh to make war against them.
13Then the people of Israel sent to the people of Reuben and the people of Gad and the half-tribe of Manasseh, in the land of Gilead, Phinehas the son of Eleazar the priest,
14and with him ten chiefs, one from each of the tribal families of Israel, every one of them the head of a family among the clans of Israel.
15And they came to the people of Reuben, the people of Gad, and the half-tribe of Manasseh, in the land of Gilead, and they said to them,
16"Thus says the whole congregation of the Lord, ‘What is this breach of faith that you have committed against the God of Israel in turning away this day from following the Lord by building yourselves an altar this day in rebellion against the Lord?
