In the New Testament, this Old Testament idea of sacrifice is applied to Christ's blood. References to the "blood of Christ" always mean the sacrificial death of Jesus on the cross. References to the blood of Christ were made by Paul <Rom. 3:25>; Peter <1 Pet. 1:19>; John <Rev. 1:5> and the author of Hebrews <Heb. 9:14>. Although all have sinned, "we have redemption through His blood, the forgiveness of sins" <Eph. 1:7>.
