King James Version
“Thus saith the Lord GOD; In the first in the first of the month, thou shalt take a young bullock without blemish, and cleanse the sanctuary:”
Context
15And one lamb out of the flock, out of two hundred, out of the fat pastures of Israel; for a meat offering, and for a burnt offering, and for peace offerings, to make reconciliation for them, saith the Lord GOD.
16All the people of the land shall give this oblation for the prince in Israel.
17And it shall be the prince’s part 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.
18Thus saith the Lord GOD; In the first in the first of the month, thou shalt take a young bullock without blemish, and cleanse the sanctuary:
19And the priest shall take of the blood of the sin offering, and put 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.
20And so thou shalt do the seventh of the month for every one that erreth, and for simple: so shall ye reconcile the house.
21In the first in the fourteenth day of the month, ye shall have the passover, a feast of seven days; unleavened bread shall be eaten.
