9 The sons of Reuben and the sons of Gad and the half-tribe of Manasseh returned home and departed from the sons of Israel at Shiloh which is in the land of Canaan, to go to the land of Gilead, to the land of their possession which they had possessed, according to the command of the Lord through Moses. 10 When 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, a large altar in appearance.
11 And the sons of Israel heard it said, “Behold, the sons of Reuben and the sons of Gad and the half-tribe of Manasseh have built an altar at the frontier of the land of Canaan, in the region of the Jordan, on the side belonging to the sons of Israel.” 12 When the sons of Israel heard of it, the whole congregation of the sons of Israel gathered themselves at Shiloh to go up against them in war.
