Joshua 22:10-14

10When they came to the region of the Jordan which is in the land of Canaan, the sons of Reuben and the sons of Gad and the half-tribe of Manasseh built an altar there by the Jordan, an altar that was great to behold.

11And the [other] sons of Israel heard it said, “Look, the sons of Reuben and the sons of Gad and the half-tribe of Manasseh have built an altar at the edge of the land of Canaan, in the region [west] of the Jordan, on the side belonging to the sons of Israel.”

12When the sons of Israel heard of it, the whole congregation of the Israelites gathered at Shiloh to make war against them.

13Then the sons of Israel sent Phinehas the son of Eleazar the priest to the sons of Reuben and the sons of Gad and the half-tribe of Manasseh, in the land of Gilead,

14and with him ten leaders, one leader from each father’s household from each of the tribes of Israel; and each one was the head of his father’s household among the thousands of Israel.
