Without blemish.

God said “Your lamb shall be without blemish” (Exod. 12.5) The next day John (the Baptist) seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. (John 1.29) Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation..... But with the precious blood of Christ, as of a lamb without blemish and without spot: (1 Peter 1.18/19)
