Psalm 40:6 KJV- Sacrifice and offering thou didst not desire; mine ears hast thou opened: burnt offering and sin offering hast thou not required. NIV- Sacrifice and offering you did not desire, but my ears you have pierced; burnt offerings and sin offerings you did not require. ESV- Sacrifice and offering you have not desired, but you have given me an open ear. Burnt offering and sin offering you have not required. As quoted in Hebrews 10:5- Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: This is a very interesting passage to study. It appears that the author of Hebrews, when he wasn't busy making coffee, studied the Septuagint and referred to that translation when he quoted Psalm 40. I suppose that I have read this verse hundreds of times and preached from it once or twice, but I never saw the depth of those words before. The issue is not having an ear to hear, it is rather an issue of ownership, is it not? In which case it appears that the NIV translates the true meaning most closely. At any rate, an interesting verse, or portion thereof, to dissect and discuss.
