Joshua 22:11

9The children of Reuben and the children of Gad and the half-tribe of Manasseh returned, and departed from the children of Israel out of Shiloh, which is in the land of Canaan, to go to the land of Gilead, to the land of their possession, which they owned, according to the commandment of the LORD by Moses.

10When they came to the region near the Jordan, that is in the land of Canaan, the children of Reuben and the children of Gad and the half-tribe of Manasseh built an altar there by the Jordan, a great altar to look at.

11The children of Israel heard this, “Behold, the children of Reuben and the children of Gad and the half-tribe of Manasseh have built an altar along the border of the land of Canaan, in the region around the Jordan, on the side that belongs to the children of Israel.”

12When the children of Israel heard of it, the whole congregation of the children of Israel gathered themselves together at Shiloh, to go up against them to war.

13The children of Israel sent to the children of Reuben, and to the children of Gad, and to the half-tribe of Manasseh, into the land of Gilead, Phinehas the son of Eleazar the priest.
