Ezekiel 44:11, 15

Yet they shall be ministers in My sanctuary, as gatekeepers of the house and ministers of the house; they shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.

“But the priests, the Levites, the sons of Zadok, who kept charge of My sanctuary when the children of Israel went astray from Me, they shall come near Me to minister to Me; and they shall stand before Me to offer to Me the fat and the blood,” says the Lord GOD.
