Ezekiel 44:15,16

The priests the Levites The Levites who are priests; the sons of Zadok Who continued faithful; they shall stand before me to offer the fat, &c. They shall serve at the altar of burnt-offering, and offer sacrifices thereon. They shall enter into my sanctuary Into the holy place; to minister unto me To burn incense there upon the golden altar, to sprinkle the blood of the victims before the veil, to trim the lamps, and to change the loaves on the sacred table every sabbath. They shall keep my charge They shall have this honour in reward of their fidelity. Observe, reader, God will put marks of honour upon those who are faithful to him in trying times, and will employ those in his service who have kept close to it when others drew back.
