Ezekiel 45:20-22

Amplified Bible

²⁰ You shall do this on the seventh [day] of the month for everyone who goes astray [and sins through error or ignorance] and for him who is naive; so shall you make atonement for the temple (house).

²¹ “In the first month, on the fourteenth day of the month, you shall have the Passover, a feast of seven days; unleavened bread shall be eaten. ²² On that day the prince shall provide for himself and for all the people of the land a bull for a sin offering.
