17 And it shall be the prince's part [to give] burnt-offerings, and meat-offerings, and drink-offerings, in the feasts, and in the new moons, and in the sabbaths, in all solemnities of the house of Israel: he shall prepare the sin-offering, and the meat-offering, and the burnt-offering, and the peace-offerings, to make reconciliation for the house of Israel.
18 Thus saith the Lord GOD; In the first [month], in the first [day] of the month, thou shalt take a young bullock without blemish, and cleanse the sanctuary:
19 And the priest shall take of the blood of the sin-offering, and put [it] upon the posts of the house, and upon the four corners of the settle of the altar, and upon the posts of the gate of the inner court.
20 And so thou shalt do the seventh [day] of the month for every one that erreth, and for [him that is] simple: so shall ye reconcile the house.
21 In the first [month], in the fourteenth day of the month, ye shall have the passover, a feast of seven days; unleavened bread shall be eaten.
