17. It shall be the duty of the prince to provide burnt offerings, grain offerings, and libations on feast days, new moons, and sabbaths, on all the festivals of the house of Israel. He shall provide the purification offering, grain offering, burnt offering, and communion offerings, to make atonement on behalf of the house of Israel.
18. Thus says the Lord God: On the first day of the first month you shall take an unblemished young bull to purify the sanctuary.
19. The priest shall take some of the blood from the purification offering and smear it on the doorposts of the house, on the four corners of the ledge of the altar, and on the doorposts of the gates of the inner courtyard.
20. You shall repeat this on the seventh day of the month for those who have sinned inadvertently or out of ignorance; thus you shall purge the temple.
21. On the fourteenth day of the first month you shall observe the feast of Passover; for seven days unleavened bread must be eaten.
