Leviticus 19:22

And the priest shall make an atonement for him
By offering his sacrifice for him, typical of the atoning sacrifice of Christ: with the ram of his trespass offering before the Lord;
presented before him at the door of the tabernacle, and offered up on his altar: for his sin which he hath done;
or "sinned", which is so expressed, according to Jarchi, to take in his sin, whether done ignorantly or presumptuously: and the sin which he hath done shall be forgiven him;
upon the atonement made, as all the sins of God's people are forgiven through Christ, upon the foot of his atoning sacrifice, see ( Hebrews 9:22 ) .
