The Passover animal was required to be without blemish. In its original setting, this requirement concerned the suitability of the sacrifice by which Israel marked its houses in obedience to God on the night of deliverance from Egypt. The unblemished lamb thus becomes part of the larger Passover pattern of deliverance through the death of a sacrificial victim.

The New Testament applies sacrificial purity to Christ. Hebrews 9:14 describes Him as offering Himself to God "without blemish," while 1 Peter 1:18-19 speaks of Christ as a lamb without blemish or spot. Paul also explicitly calls Christ "our Passover" in 1 Corinthians 5:7. Christians therefore understand the unblemished Passover lamb as a type of the sinless Christ, whose perfect self-offering accomplishes a greater deliverance from sin and judgment. The connection is typological, but it is strongly grounded in the New Testament's own use of Passover and sacrificial imagery for Jesus.
