Ezekiel 45:18-20

American Standard Version

¹⁸ Thus saith the Lord Jehovah: In the first month, in the first day of the month, thou shalt take a young bullock without blemish; and thou shalt cleanse the sanctuary. ¹⁹ And the priest shall take of the blood of the sin-offering, and put it upon the door-posts of the house, and upon the four corners of the ledge of the altar, and upon the posts of the gate of the inner court. ²⁰ And so thou shalt do on the seventh day of the month for every one that erreth, and for him that is simple: so shall ye make atonement for the house.
