EZK 44:11

11 they shall be keepers of [[the]] houses in my saintuary, and porters of gates of the house (of the Lord), and ministers of the house (of the Lord); they shall slay burnt sacrifices, and sacrifices for victory of the people; and they shall stand in the sight of the priests for to minister to them. (they shall still do service in my sanctuary, and as gatekeepers they shall be in charge of the gates of the Temple, and shall also minister, or shall serve, at the Temple; they shall kill the burnt sacrifices, and the sacrifices for the people; and they shall stand before the priests to serve the people.)
