9. So the children of Reuben, the children of Gad, and half the tribe of Manasseh returned, and departed from the children of Israel at Shiloh, which is in the land of Canaan, to go to the country of Gilead, to the land of their possession, which they had obtained according to the word of the Lord by the hand of Moses.
10. And when they came to the region of the Jordan which is in the land of Canaan, the children of Reuben, the children of Gad, and half the tribe of Manasseh built an altar there by the Jordan—a great, impressive altar.
11. Now the children of Israel heard someone say, “Behold, the children of Reuben, the children of Gad, and half the tribe of Manasseh have built an altar on the frontier of the land of Canaan, in the region of the Jordan—on the children of Israel’s side.”
12. And when the children of Israel heard of it, the whole congregation of the children of Israel gathered together at Shiloh to go to war against them.
13. Then the children of Israel sent Phinehas the son of Eleazar the priest to the children of Reuben, to the children of Gad, and to half the tribe of Manasseh, into the land of Gilead,
14. and with him ten rulers, one ruler each from the chief house of every tribe of Israel; and each one was the head of the house of his father among the divisions of Israel.
15. Then they came to the children of Reuben, to the children of Gad, and to half the tribe of Manasseh, to the land of Gilead, and they spoke with them, saying,
16. “Thus says the whole congregation of the Lord: ‘What treachery is this that you have committed against the God of Israel, to turn away this day from following the Lord, in that you have built for yourselves an altar, that you might rebel this day against the Lord?
17. Is the iniquity of Peor not enough for us, from which we are not cleansed till this day, although there was a plague in the congregation of the Lord,
18. but that you must turn away this day from following the Lord? And it shall be, if you rebel today against the Lord, that tomorrow He will be angry with the whole congregation of Israel.
19. Nevertheless, if the land of your possession is unclean, then cross over to the land of the possession of the Lord, where the Lord’s tabernacle stands, and take possession among us; but do not rebel against the Lord, nor rebel against us, by building yourselves an altar besides the altar of the Lord our God.
20. Did not Achan the son of Zerah commit a trespass in the accursed thing, and wrath fell on all the congregation of Israel? And that man did not perish alone in his iniquity.’ ”
21. Then the children of Reuben, the children of Gad, and half the tribe of Manasseh answered and said to the heads of the divisions of Israel:
22. “The Lord God of gods, the Lord God of gods, He knows, and let Israel itself know—if it is in rebellion, or if in treachery against the Lord, do not save us this day.
23. If we have built ourselves an altar to turn from following the Lord, or if to offer on it burnt offerings or grain offerings, or if to offer peace offerings on it, let the Lord Himself require an account.
