Joshua 22:16

Thus saith the whole congregation of the Lord, What trespass is this that ye have committed against the God of Israel, in open rebellion against Jehovah, to turn away this day from following the Lord, by an act of faithlessness and disloyalty, in that ye have builded you an altar, that ye might rebel this day against the Lord? Even though the language may be considered strong, the zeal which prompted it was, at any rate, praiseworthy, since the altar, although not built for a place of sacrifice, yet might easily be perverted to that use, and lead the whole people into the sin of idolatry. At all events, the two and one half tribes ought not to have undertaken the building of this altar without first consulting with Joshua or with the high priest.
