But with the precious blood of Christ, as of a lamb without blemish and without spot:

People's New Testament

1:19 A lamb without blemish and without spot. The New Testament writers with one accord refer to Christ as the Lamb of God, who taketh away the sin of the world. See Joh 1:29 Eph 1:4 5:27 Col 1:22 Heb 9:14.

Wesley's Notes

1:19 Without blemish - In himself. Without spot - From the world.

Jamieson-Fausset-Brown Bible Commentary

19. 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" (1Pe 1:20) from eternity, as the passover lamb was taken up on the tenth day of the month.

Matthew Henry's Concise Commentary

1:17-25 Holy confidence in God as a Father, and awful fear of him as a Judge, agree together; and to regard God always as a Judge, makes him dear to us as a Father. If believers do evil, God will visit them with corrections. Then, let Christians not doubt God's faithfulness to his promises, nor give way to enslaving dread of his wrath, but let them reverence his holiness. The fearless professor is defenceless, and Satan takes him captive at his will; the desponding professor has no heart to avail himself of his advantages, and is easily brought to surrender. The price paid for man's redemption was the precious blood of Christ. Not only openly wicked, but unprofitable conversation is highly dangerous, though it may plead custom. It is folly to resolve, I will live and die in such a way, because my forefathers did so. God had purposes of special favour toward his people, long before he made manifest such grace unto them. But the clearness of light, the supports of faith, the power of ordinances, are all much greater since Christ came upon earth, than they were before. The comfort is, that being by faith made one with Christ, his present glory is an assurance that where he is we shall be also, Joh 14:3. The soul must be purified, before it can give up its own desires and indulgences. And the word of God planted in the heart by the Holy Ghost, is a means of spiritual life, stirring up to our duty, working a total change in the dispositions and affections of the soul, till it brings to eternal life. In contrast with the excellence of the renewed spiritual man, as born again, observe the vanity of the natural man. In his life, and in his fall, he is like grass, the flower of grass, which soon withers and dies away. We should hear, and thus receive and love, the holy, living word, and rather hazard all than lose it; and we must banish all other things from the place due to it. We should lodge it in our hearts as our only treasures here, and the certain pledge of the treasure of glory laid up for believers in heaven.
