Matthew Poole and continuators on Hebrews 10:7

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

When the Father declared the Sacrifices of Beasts and Birds would not please him, nor be accepted for expiating Sins, then I said, I appeared in Person, and declared, Lo, I come with a fit and proper Sacrifice; I approach my self with my Human Nature, fully resolved to offer that to Thee as a Propitiatory Sacrifice, Iohn 12.27. comp. Psalm 40.7.

[non-Latin text not transcribed] the Head; our Translators keep to the Hebrew [non-Latin text not transcribed] the Volume of the Book, Psal. 40.7. Books with the Hebrews, were Rolls of Parchment stitched at the top, and so rolled up. In this Book was Christ every where written and spoken of, as he testifieth himself before his Death, Iohn 5.39. after his Resurrection, Luke 24.44, 45, 46. The Septuagint render it, the Head, as being in the top and beginning of the whole Roll, to wit, in the Books of Moses. Compare Luke 24.27. And in the entrance of them the Spirit testifieth of his Deity, and of his Union to the Humanity, being to be conceived and born of a Virgin, and offering himself a Sacrifice to expiate Sin, and reconcile Sinners, Gen. 3.15. comp. Iohn 5.46, 47.

To obey his Fathers Command, of dying an Expiatory Sacrifice for Sinners. It was his Father's Will that he should so offer himself for satisfying his Justice, making way for his Mercy and so redeeming and recovering lost Souls. This Will of God was in his Heart, he delighted to obey it, Psalm 40.8. and his own natural Will that would regret it, he would deny, and would not use his Divine Power to deliver himself from it, Matth. 26.39, 46. Ioh. 18.11.
