Ezekiel 44:10-12

10But the Levites who went away far from me, when Israel went astray, going astray from me after their idols, they shall even bear their iniquity;

11but they shall be ministers in my sanctuary, having oversight at the gates of the house, and doing the service of the house: they shall slaughter 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 were unto the house of Israel a stumbling-block of iniquity; therefore have I lifted up my hand against them, saith the Lord Jehovah, that they shall bear their iniquity.
