Ezekiel 45:19-21

Revised Standard Version

¹⁹ The priest shall take some of the blood of the sin offering and put it on the doorposts of the temple, the four corners of the ledge of the altar, and the posts of the gate of the inner court. ²⁰ You shall do the same on the seventh day of the month for any one who has sinned through error or ignorance; so you shall make atonement for the temple.

²¹ “In the first month, on the fourteenth day of the month, you shall celebrate the feast of the passover, and for seven days unleavened bread shall be eaten.
