Ezekiel 44:15-17

Young's Literal Translation

¹⁵ `And the priests, the Levites, sons of Zadok, who have kept the charge of My sanctuary in the wandering of the sons of Israel from off Me, they draw near unto Me to serve Me, and have stood before Me, to bring near to Me fat and blood -- an affirmation of the Lord Jehovah:

¹⁶ they come in unto My sanctuary, and they draw near unto My table to serve Me, and they have kept My charge.

¹⁷ And it hath come to pass, in their going in unto the gates of the inner court, linen garments they put on; and no wool cometh up on them in their ministering in the gates of the inner court and within.
