Ezekiel 44:10-12

10But the Levites that went far from me, when Israel went astray, that went astray from me after their idols, they shall bear their iniquity. 11Yet they shall be ministers in my sanctuary, having oversight at the gates of the house, and ministering in the house: they shall slay the burnt-offering and the sacrifice for the people, and they shall stand before them to minister unto them. 12Because they ministered unto them before their idols, and became a stumblingblock of iniquity unto the house of Israel; therefore have I lifted up my hand against them, saith the Lord Jehovah, and they shall bear their iniquity.
