Yechezkel 44:9-11

Orthodox Jewish Bible

⁹ Thus saith Adonoi Hashem: No ben nechor, arel lev, nor arel basar, shall enter into My Mikdash, of any ben nechor that is among the Bnei Yisroel.

¹⁰ And the Levi’im that went far away from Me, when Yisroel went astray, which went astray away from Me after their gillulim (idols); they shall even bear their avon.

¹¹ Yet they shall be mesharetim (ministers) in My Mikdash, pekuddot (the ones who have charge) at the Sha’arei HaBeis [HaMikdash] and mesharetim in HaBeis [HaMikdash]; they shall do the shochet slaughter of the olah (burnt offering) and the zevach for the people, and they shall stand before them to minister unto them.
