Psalms 40:6

Sacrifice — These and the following words, may in an improper sense belong to the time of David; when God might be said, not to desire or require legal sacrifices comparatively. Thou didst desire obedience rather than sacrifices, but in a proper sense, they belong only to the person and times of the Messiah, and so the sense is, God did not desire or require them, for the satisfaction of his own justice, and the expiation of mens sins, which could not possibly be done by the blood of bulls or goats, but only by the blood of Christ, which was typified by them, and which Christ came into the world to shed, in pursuance of his father's will, as it here follows, Psalms 40:7. So here is a prediction concerning the cessation of the legal sacrifice, and the substitution of a better instead of them. Opened — Heb. bored. I have devoted myself to thy perpetual service, and thou hast accepted of me as such, and signified so much by the boring of mine ears, according to the law and custom in that case, Exodus 21:5. The seventy Jewish interpreters, whom the apostle follows, Hebrews 10:5, translate these words, a body hast thou prepared me.
