(7) Lo, I come.--Rather, Lo, I am come--I am here. The original meaning of the following words is not quite certain. The Hebrew admits of two renderings. (1) Then I said, Lo, I am come! in the roll of the Book it is prescribed unto me; (2) Then I said, Lo, I am come with the roll of the Book that is written concerning me. The "roll of the Book" is the roll containing the Divine Law. The next clause is quite distinct in construction: "I delight to do Thy will, O God; yea, Thy law is within my heart." The omission of the words "I delight," alters the connection of the words; but it will be seen that, though the Hebrew verses are condensed, their meaning is exactly preserved.

10:1-10 The apostle having shown that the tabernacle, and ordinances of the covenant of Sinai, were only emblems and types of the gospel, concludes that the sacrifices the high priests offered continually, could not make the worshippers perfect, with respect to pardon, and the purifying of their consciences. But when God manifested in the flesh, became the sacrifice, and his death upon the accursed tree the ransom, then the Sufferer being of infinite worth, his free-will sufferings were of infinite value. The atoning sacrifice must be one capable of consenting, and must of his own will place himself in the sinner's stead: Christ did so. The fountain of all that Christ has done for his people, is the sovereign will and grace of God. The righteousness brought in, and the sacrifice once offered by Christ, are of eternal power, and his salvation shall never be done away. They are of power to make all the comers thereunto perfect; they derive from the atoning blood, strength and motives for obedience, and inward comfort.Then said I, lo, I come,.... Christ observing that legal sacrifices were not acceptable to God; that there was a body prepared for him; and that it was written of him in the book of God, that he should come; and the time being now come, with a note of attention and admiration, the matter being of great moment and concern, he cheerfully expresses his readiness to come, immediately, without any compulsion, even he himself, and not another.

In the volume of the book it is written of me; in the book of the law, as the, Targum and Kimchi on Psalm 40:7 interpret it; and which may design the Bible in general, the whole book of the Scriptures of the Old Testament: so "the book", is used for the whole Bible (r), and it is said (s), all the whole law, that is, all Scripture, is called "a volume"; accordingly there are things written of Christ in all the writings of the Old Testament, in the law, and in the prophets, and in the psalms. Jarchi interprets it of the law of Moses, and so it may design the pentateuch, or the five books of Moses; and there are several places therein, in which it is written of Christ, and particularly in Genesis, the first of these books, and in the head, the beginning, the frontal piece, the first part of that book; namely, Genesis 3:15 which may be principally designed. Books were formerly written in rolls of parchment, and hence called volumes; See Gill on Luke 4:17, See Gill on Luke 4:20. The end of his coming is next expressed by him,

to do thy will, O God; which, when he came, he set about with the utmost delight, diligence, and faithfulness, in preaching the Gospel, performing miracles, doing good to the bodies and souls of men, and in finishing the great work of man's redemption, which was the main part of his Father's will he came to do; and which he did, by fulfilling the law in its precept and penalty; by offering himself a sacrifice to God; by suffering death, the death of the cross; by destroying all his and our enemies, and so working out everlasting salvation.
