Ezekiel 44:10

And the (d) Levites that have gone away far from me, when Israel went astray, who went astray from me after their idols; they shall even bear their iniquity.

(d) The Levites who had committed idolatry were put from their dignity and could not be received into the priests office although they had been of the house of Aaron, but must serve in the inferior offices as to watch and to keep the doors, read (2 Kings 23:9).
