ISB ~ 1 Peter 1 v19

lamb without blemish:Depicts Jesus as a Passover lamb (1 Cor 5:7).

• Exodus stipulates that lambs chosen for Passover must be free from all physical defects (Ex 12:5). The point here is that Jesus is free from every blemish of sin (1 Pet 2:22). Other details reminiscent of the Passover tradition include the notion that Jesus “ransomed” us from sinful ways (1:18), just as Israel was redeemed from sinful Egypt (Ex 15:13), and that the “blood” of Jesus was shed for our salvation (1 Pet 1:19), recalling how the blood of the paschal lamb was shed as the sign of God’s deliverance at the first Exodus (Ex 12:21-23) (CCC 602).
