Joshua 22:10-19

10And when they came unto 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 to see to.

11And the children of Israel heard say, Behold, the children of Reuben and the children of Gad and the half tribe of Manasseh have built an altar over against the land of Canaan, in the borders of Jordan, at the passage of 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 unto 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 unto the children of Reuben, and to the children of Gad, and to the half tribe of Manasseh, unto the land of Gilead, and they spake with them, saying, 16Thus saith the whole congregation of Yhwh, What trespass is this that ye have committed against the God of Israel, to turn away this day from following Yhwh, in that ye have builded you an altar, that ye might rebel this day against Yhwh? 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 Yhwh, 18But that ye must turn away this day from following Yhwh? and it will be, seeing ye rebel to day against Yhwh, that to morrow he will be wroth with the whole congregation of Israel. 19Notwithstanding, if the land of your possession be unclean, then pass ye over unto the land of the possession of Yhwh, wherein Yhwh's tabernacle dwelleth, and take possession among us: but rebel not against Yhwh, nor rebel against us, in building you an altar beside the altar of Yhwh our God.
