Hebrews 10:4

“For it is not possible, etc..] There is a necessity of sin being taken away, otherwise it will be remembered; and there will be a conscience of it, and it must be answered for, or it will remain marked, and the curse and penalty of the law must take place: but it is impossible that the blood of bulls and goats should take away sins; which was shed on the day of atonement: sin is a breach of the moral law, but these sacrifices belong to, the ceremonial law, which are less acceptable to God than moral duties; sin is committed against God, and has an objective infiniteness in it, and therefore can never be atoned for by the blood of such creatures; it leaves a stain on the mind and conscience,…”

“For, &c.--reason why, necessarily, there is a continually recurring "remembrance of sins" in the legal sacrifices (Heb 10:3). Typically, "the blood of bulls," &c., sacrificed, had power; but it was only in virtue of the power of the one real antitypical sacrifice of Christ; they had no power in themselves; they were not the instrument of perfect vicarious atonement, but an exhibition of the need of it, suggesting to the faithful Israelite the sure hope of coming redemption, according to God's promise. take away--"take off." The Greek, Heb 10:11, is stronger, explaining the weaker word here, "take away utterly." The blood of beasts could not take away the sin of man. A MAN must do that (see…”

“For it is not possible that the blood of bulls and of goats should take away sins - The reference here is to the sacrifices which were made on the great day of the atonement, for on that day the blood of bulls and of goats alone was offered; see the notes on Hebrews 9:7. Paul here means to say, doubtless, that it was not possible that the blood of these animals should make a complete expiation so as to purify the conscience, and so as to save the sinner from deserved wrath. According to the divine arrangement, expiation was made by those sacrifices for offences of various kinds against the ritual law of Moses, and pardon for such offences was thus obtained. But the meaning here is, that…”

“It is impossible the blood of goats should take away sins - Either the guilt or the power of them. Hebrews 10:5”

“10:4 The blood of bulls and goats in the sacrifices of the old covenant offered a degree of cleansing (9:13, 23), but that cleansing was limited in that it could not take away sins. It could not eradicate sin in a way that would offer permanent cleansing and peace with God (see Acts 10:36; Rom 5:1; 11:26-27).”

“not: Heb 10:8, Heb 9:9, Heb 9:13; Psa 50:8-12, Psa 51:16; Isa 1:11-15, Isa 66:3; Jer 6:20, Jer 7:21, Jer 7:22; Hos 6:6; Amo 5:21, Amo 5:22; Mic 6:6-8; Mar 12:33 take: There were essential defects in these sacrifices. 1st - They were not of the same nature with those who sinned. 2nd - They were not of sufficient value to make satisfaction for the affronts done to the justice and government of God. 3rd - The beasts offered up under the law could not consent to put themselves in the sinner's room and place. The atoning sacrifice must be one capable of consenting, and must voluntarily substitute himself in the sinner's stead: Christ did so. Heb 10:11; Hos 14:2; Joh 1:29; Rom 11:27; Jo1 3:5…”
