Hebrews 10:9

To do thy will. See on v. 7.

Taketh away the first. First the author quoted the passage from the Psalms (vs. 5-7), then he repeated the significant portions of it for his present purpose (vs. 8, 9), and now he makes his application. He uses this passage to prove that the old system was done away with when Christ came to do the will of God, that is, to provide an effective sacrifice. The passing away of the old is indicated by the statement that God had no pleasure in the sacrifices offered by the law. The establishment of the new is indicated by the statement that Christ did the will of God in providing the true sacrifice. Compare on ch. 8:13. The fact that the old system was obsolete was a difficult point for the Hebrew Christians to grasp. The author of Hebrews is attempting to prove to them that this was predicted in the OT, the writings held sacred by those who lived under the old system.
