Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.

People's New Testament

10:7 Then said I, Lo, I come... to do thy will, O God. The Psalmist (Ps 40:7,8) represents Christ, who comes simply to do the will of God, completely surrendered to his will.

In the volume of the book it is written of me. In the roll of the law it is written of me; that is, there I am predicted.

Wesley's Notes

10:7 In the volume of the book - In this very psalm it is written of me. Accordingly I come to do thy will - By the sacrifice of myself.

Jamieson-Fausset-Brown Bible Commentary

7. I come-rather, "I am come" (see on [2575]Heb 10:5). "Here we have the creed, as it were, of Jesus: 'I am come to fulfil the law,' Mt 5:17; to preach, Mr 1:38; to call sinners to repentance, Lu 5:32; to send a sword and to set men at variance, Mt 10:34, 35; I came down from heaven to do the will of Him that sent me, Joh 6:38, 39 (so here, Ps 40:7, 8); I am sent to the lost sheep of the house of Israel, Mt 15:24; I am come into this world for judgment, Joh 9:39; I am come that they might have life, and might have it more abundantly, Joh 10:10; to save what had been lost, Mt 18:11; to seek and to save that which was lost, Lu 19:10; compare 1Ti 1:15; to save men's lives, Lu 9:56; to send fire on the earth, Lu 12:49; to minister, Mt 20:28; as "the Light," Joh 12:46; to bear witness unto the truth, Joh 18:37. See, reader, that thy Saviour obtain what He aimed at in thy case. Moreover, do thou for thy part say, why thou art come here? Dost thou, then, also, do the will of God? From what time? and in what way?" [Bengel]. When the two goats on the day of atonement were presented before the Lord, that goat on which the lot of the Lord should fall was to be offered as a sin offering; and that lot was lifted up on high in the hand of the high priest, and then laid upon the head of the goat which was to die; so the hand of God determined all that was done to Christ. Besides the covenant of God with man through Christ's blood, there was another covenant made by the Father with the Son from eternity. The condition was, "If He shall make His soul an offering for sin, He shall see His seed," &c. (Isa 53:10). The Son accepted the condition, "Lo, I come to do Thy will, O God" [Bishop Pearson]. Oblation, intercession, and benediction, are His three priestly offices.

in the volume, &c.-literally, "the roll": the parchment manuscript being wrapped around a cylinder headed with knobs. Here, the Scripture "volume" meant is the fortieth Psalm. "By this very passage 'written of Me,' I undertake to do Thy will [namely, that I should die for the sins of the world, in order that all who believe may be saved, not by animal sacrifices, Heb 10:6, but by My death]." This is the written contract of Messiah (compare Ne 9:38), whereby He engaged to be our surety. So complete is the inspiration of all that is written, so great the authority of the Psalms, that what David says is really what Christ then and there said.

Matthew Henry's Concise Commentary

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.
