Leviticus 16:33-34

Wycliffe Bible

³³ and he shall cleanse the saintuary, and the tabernacle of witnessing (and he shall cleanse the sanctuary, and the Tabernacle of the Witnessing), and the altar, and the priests, and all the people.

³⁴ And this shall be to you a lawful thing everlasting (And this shall be an everlasting law for you), that ye pray for the sons of Israel, and for all their sins, once in the year. Therefore Aaron did, as the Lord commanded to Moses.
