What does the Bible say about the sacrificial system in Leviticus?

The sacrificial system detailed in Leviticus, particularly in the ritual of the scapegoat, serves as a profound representation of the concept of sin transfer, which is ultimately fulfilled in Jesus Christ. Leviticus 16:21-22 illustrates how Aaron would confess the iniquities of Israel over the head of a live goat, symbolically transferring their sins to it. This act foreshadows the ultimate sacrifice of Christ, who bore the sins of His people, as Isaiah 53:6 declares, 'The Lord laid on Him the iniquity of us all'. The act of sending the goat into the wilderness symbolizes that once sins are laid upon Christ, they are removed from the people, never to be remembered again, highlighting God's mercy and grace in forgiveness.
