In the Old Testament, when the priests laid their hands on the head of the burnt offering and offered the burnt offering as a sacrifice to God, the sins of the people of Israel were forgiven. (Lev 1:3-4)

Lev 1:3 If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the Lord.
4 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.

In the Old Testament, it was prophesied that the coming Christ would bear our sins in order to forgive our sins. (Isa 53:11)

Isa 53:11 He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.

Jesus is the Lamb of God who took away our sins. (John 1:29)

Gal 1:4 Who gave himself for our sins, that he might deliver us from this present evil world, according to the will of God and our Father:

1 John 2:2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
