Ezekiel 45:19-21

New Catholic Bible

¹⁹ The priest must take some of the blood of the sin offering and put it on the doorposts of the temple, on the four corners of the ledge of the altar, and on the doorposts of the gates of the inner court. ²⁰ You are to do the same on the seventh day of the month for anyone who has sinned inadvertently or because of ignorance. In this way, you will make atonement for the temple.

²¹ On the fourteenth day of the first month, you must celebrate the Feast of the Passover, and for seven days, everyone must eat unleavened bread.
