Ezekiel 44:16 KJV

14But I will make them keepers of the charge of the house, for all the service thereof, and for all that shall be done therein.

15But the priests the Levites, the sons of Zadok, that kept the charge of my sanctuary when the children of Israel went astray from me, they shall come near to me to minister unto me, and they shall stand before me to offer unto me the fat and the blood, saith the Lord GOD:

16They shall enter into my sanctuary, and they shall come near to my table, to minister unto me, and they shall keep my charge.

17And it shall come to pass, that when they enter in at the gates of the inner court, they shall be clothed with linen garments; and no wool shall come upon them, whiles they minister in the gates of the inner court, and within.

18They shall have linen bonnets upon their heads, and shall have linen breeches upon their loins; they shall not gird themselves with any thing that causeth sweat.
