Priestly Law of the Reparation Offering and Priestly Portions
The strongest Christ connection is a word trail Scripture itself creates: asham in Leviticus, asham for Isaiah's Servant, and the New Testament's identification of that Servant with Jesus.
Where this fits in the story: Explicit continuation of the asham laws in Leviticus 5–6.
Where Scripture takes it next: Acts 8:32–35 explicitly identifies the Isaiah 53 Servant text with the good news about Jesus; 1 Peter 2:22–25 also reuses Isaiah 53 around Christ's suffering/sin-bearing.
