Joshua 22:11-13 NIV

[11] And when the Israelites heard that they had built the altar on the border of Canaan at Geliloth near the Jordan on the Israelite side, [12] the whole assembly of Israel gathered at Shiloh to go to war against them. [13] So the Israelites sent Phinehas son of Eleazar, the priest, to the land of Gilead—to Reuben, Gad and the half-tribe of Manasseh.
