Psalm 40:5–8 (Listen)

5   You have multiplied, O LORD my God,
    your wondrous deeds and your thoughts toward us;
    none can compare with you!
  I will proclaim and tell of them,
    yet they are more than can be told.
6   In sacrifice and offering you have not delighted,
    but you have given me an open ear.¹
  Burnt offering and sin offering
    you have not required.
7   Then I said, “Behold, I have come;
    in the scroll of the book it is written of me:
8   I delight to do your will, O my God;
    your law is within my heart.”

(ESV)

Hebrews 10:5–10 (Listen)

5 Consequently, when Christ¹ came into the world, he said,

  “Sacrifices and offerings you have not desired,
    but a body have you prepared for me;
6   in burnt offerings and sin offerings
    you have taken no pleasure.
7   Then I said, ‘Behold, I have come to do your will, O God,
    as it is written of me in the scroll of the book.’”

8 When he said above, “You have neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings” (these are offered according to the law), 9 then he added, “Behold, I have come to do your will.” He does away with the first in order to establish the second. 10 And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.

(ESV)
