Joshua 22:7-20

Now to the one half of the tribe of Manas'seh Moses had given a possession in Bashan; but to the other half Joshua had given a possession beside their brethren in the land west of the Jordan. And when Joshua sent them away to their homes and blessed them, he said to them, "Go back to your homes with much wealth, and with very many cattle, with silver, gold, bronze, and iron, and with much clothing; divide the spoil of your enemies with your brethren." So the Reubenites and the Gadites and the half-tribe of Manas'seh returned home, parting from the people of Israel at Shiloh, which is in the land of Canaan, to go to the land of Gilead, their own land of which they had possessed themselves by command of the LORD through Moses. And when they came to the region about the Jordan, that lies in the land of Canaan, the Reubenites and the Gadites and the half-tribe of Manas'seh built there an altar by the Jordan, an altar of great size. And the people of Israel heard say, "Behold, the Reubenites and the Gadites and the half-tribe of Manas'seh have built an altar at the frontier of the land of Canaan, in the region about the Jordan, on the side that belongs to the people of Israel." And when the people of Israel heard of it, the whole assembly of the people of Israel gathered at Shiloh, to make war against them. Then the people of Israel sent to the Reubenites and the Gadites and the half-tribe of Manas'seh, in the land of Gilead, Phin'ehas the son of Elea'zar the priest, and with him ten chiefs, one from each of the tribal families of Israel, every one of them the head of a family among the clans of Israel. And they came to the Reubenites, the Gadites, and the half-tribe of Manas'seh, in the land of Gilead, and they said to them, "Thus says the whole congregation of the LORD, 'What is this treachery which you have committed against the God of Israel in turning away this day from following the LORD, by building yourselves an altar this day in rebellion against the LORD? Have we not had enough of the sin at Pe'or from which even yet we have not cleansed ourselves, and for which there came a plague upon the congregation of the LORD, that you must turn away this day from following the LORD? And if you rebel against the LORD today he will be angry with the whole congregation of Israel tomorrow. But now, if your land is unclean, pass over into the LORD's land where the LORD's tabernacle stands, and take for yourselves a possession among us; only do not rebel against the LORD, or make us as rebels by building yourselves an altar other than the altar of the LORD our God. Did not Achan the son of Zerah break faith in the matter of the devoted things, and wrath fell upon all the congregation of Israel? And he did not perish alone for his iniquity.'"
