Joshua 22:10-19

10And when they came to the borders of Jordan, that are in the land of Canaan, the children of Reuben and the children of Gad and the half tribe of Manasseh built there an altar by Jordan, a great altar in appearance. 11And the children of Israel heard it said, Behold, the children of Reuben and the children of Gad and the half tribe of Manasseh have built an altar at the border of the land of Canaan, in the borders of Jordan, on the side belonging to the children of Israel. 12And when the children of Israel heard of it, the whole congregation of the children of Israel gathered themselves together at Shiloh, to go up to war against them. 13And the children of Israel sent to the children of Reuben, and to the children of Gad, and to the half tribe of Manasseh, into the land of Gilead, Phinehas the son of Eleazar the priest, 14And with him ten princes, of each chief house a prince throughout all the tribes of Israel; and each one was an head of the house of their fathers among the thousands of Israel.1 15And they came to the children of Reuben, and to the children of Gad, and to the half tribe of Manasseh, to the land of Gilead, and they spoke with them, saying, 16Thus saith the whole congregation of the LORD, What trespass is this that ye have committed against the God of Israel, to turn away this day from following the LORD, in that ye have built you an altar, that ye might rebel this day against the LORD? 17Is the iniquity of Peor too little for us, from which we are not cleansed until this day, although there was a plague in the congregation of the LORD, 18But that ye must turn away this day from following the LORD? and it will be, seeing ye rebel to day against the LORD, that to morrow he will be angry with the whole congregation of Israel. 19However, if the land of your possession is unclean, then pass ye over to the land of the possession of the LORD, in which the LORD’S tabernacle dwelleth, and take possession among us: but rebel not against the LORD, nor rebel against us, in building you an altar besides the altar of the LORD our God.
