Leviticus 4:20

And the priest shall make an atonement for all the congregation of the children of Israel, and it shall be forgiven them; for it is ignorance: and they shall bring their offering, a sacrifice made by fire unto the Lord, and their sin offering before the Lord, for their ignorance:

By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;

Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;

Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.

How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him.

And the remnant of the oil that is in the priest’s hand he shall pour upon the head of him that is to be cleansed: and the priest shall make an atonement for him before the Lord.

And he shall burn all his fat upon the altar, as the fat of the sacrifice of peace offerings: and the priest shall make an atonement for him as concerning his sin, and it shall be forgiven him.

And the priest shall make an atonement for the soul that sinneth ignorantly, when he sinneth by ignorance before the Lord, to make an atonement for him; and it shall be forgiven him.

And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,

And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
