Joshua 22:10-14

10But while they were still in Canaan, and when they came to a place called Geliloth near the Jordan River, the men of Reuben, Gad, and the half-tribe of Manasseh stopped to build a large and imposing altar.

11The rest of Israel heard that the people of Reuben, Gad, and the half-tribe of Manasseh had built an altar at Geliloth at the edge of the land of Canaan, on the west side of the Jordan River.

12So the whole community of Israel gathered at Shiloh and prepared to go to war against them.

13First, however, they sent a delegation led by Phinehas son of Eleazar, the priest, to talk with the tribes of Reuben, Gad, and the half-tribe of Manasseh.

14In this delegation were ten leaders of Israel, one from each of the ten tribes, and each the head of his family within the clans of Israel.
