Ezekiel 45:21

18 This is what the Lord has said: In the first month, on the first day of the month, you are to take a young ox without any mark on him, and you are to make the holy place clean.

19 And the priest is to take some of the blood of the sin-offering and put it on the uprights at the sides of the doors of the house, and on the four angles of the shelf of the altar, and on the sides of the doorway of the inner square.

20 And this you are to do on the seventh day of the month for everyone who is in error and for the feeble-minded: you are to make the house free from sin.

21 In the first month, on the fourteenth day of the month, you are to have the Passover, a feast of seven days; unleavened bread is to be your food.

22 And on that day the ruler is to give for himself and for all the people of the land an ox for a sin-offering.

23 And on the seven days of the feast he is to give a burned offering to the Lord, seven oxen and seven sheep without any mark on them, every day for seven days; and a he-goat every day for a sin-offering.

24 And he is to give a meal offering, an ephah for every ox and an ephah for every sheep and a hin of oil to every ephah.
