9. So the people of the tribes of Reuben, Gad, and East Manasseh went back home. They left the rest of the people of Israel at Shiloh in the land of Canaan and started out for their own land, the land of Gilead, which they had taken as the Lord had commanded them through Moses.
10. When the tribes of Reuben, Gad, and East Manasseh arrived at Geliloth, still on the west side of the Jordan, they built a large, impressive altar there by the river.
11. The rest of the people of Israel were told, “Listen! The people of the tribes of Reuben, Gad, and East Manasseh have built an altar at Geliloth, on our side of the Jordan!”
12. When the people of Israel heard this, the whole community came together at Shiloh to go to war against the eastern tribes.
13. Then the people of Israel sent Phinehas, the son of Eleazar the priest, to the people of the tribes of Reuben, Gad, and East Manasseh in the land of Gilead.
14. Ten leading men went with Phinehas, one from each of the western tribes and each one the head of a family among the clans.
15. They came to the land of Gilead, to the people of Reuben, Gad, and East Manasseh,
16. and speaking for the whole community of the Lord, they said to them, “Why have you done this evil thing against the God of Israel? You have rebelled against the Lord by building this altar for yourselves! You are no longer following him!
17. Remember our sin at Peor, when the Lord punished his own people with an epidemic? We are still suffering because of that. Wasn't that sin enough?
18. Are you going to refuse to follow him now? If you rebel against the Lord today, he will be angry with everyone in Israel tomorrow.
19. Now then, if your land is not fit to worship in, come over into the Lord's land, where his Tent is. Claim some land among us. But don't rebel against the Lord or make rebels out of us by building an altar in addition to the altar of the Lord our God.
20. Remember how Achan son of Zerah refused to obey the command about the things condemned to destruction; the whole community of Israel was punished for that. Achan was not the only one who died because of his sin.”
