Joshua 22:10-13 NIV

[10] When they came to Geliloth near the Jordan in the land of Canaan, the Reubenites, the Gadites and the half-tribe of Manasseh built an imposing altar there by the Jordan. [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.
