1 Peter 1:19

“But with the precious blood of Christ, etc.] Christ was prophesied of as a Redeemer under the Old Testament, (<235920>Isaiah 59:20) and the Jews frequently ascribe redemption to the word of the Lord God f34; and which the apostle here attributes to the blood of Christ; whose blood is the same with ours, only not tainted with sin; the blood of an innocent person, and of one who is God, as well as man, and was freely shed in the room and stead of his people, and so a sufficient price for their redemption: and it may truly be said to be “precious”: as it is to God, to whom it is a sweet smelling sacrifice, and with which he is well pleased; not that he takes delight in the mere effusion of his…”

“precious--of inestimable value. The Greek order is, "With precious blood, as of a lamb without blemish (in itself) and without spot (contracted by contact with others), (even the blood) of Christ." Though very man, He remained pure in Himself ("without blemish"), and uninfected by any impression of sin from without ("without spot"), which would have unfitted Him for being our atoning Redeemer: so the passover lamb, and every sacrificial victim; so too, the Church, the Bride, by her union with Him. As Israel's redemption from Egypt required the blood of the paschal lamb, so our redemption from sin and the curse required the blood of Christ; "foreordained" (Pe1 1:20) from eternity, as the…”

“But with the precious blood of Christ - On the use of the word blood, and the reason why the efficacy of the atonement is said to be in the blood, see the notes at Romans 3:25. The word “precious” (τίμιος timios) is a word which would be applied to that which is worth much; which is costly. Compare for the use of the noun (τιμή timē) in this sense, Matthew 27:6, “The price of blood;” Acts 4:34; Acts 5:2-3; Acts 7:16. See also for the use of the adjective, (τίμιος timios,) Revelation 17:4, “gold and precious stones” Revelation 18:12, “vessels of most precious wood.” Revelation 21:11, “a stone most precious.” The meaning here is, that the blood of Christ had a value above silver and gold;…”

“Without blemish - In himself. Without spot - From the world. 1 Peter 1:21”

“1:19 the sinless, spotless Lamb of God: The Passover Lamb had to be without defect (Exod 12:5); Christ, who fulfills the meaning of the Passover, was without defect or sin (cp. Heb 4:14-16; 7:26-28).”
