Psalms 40:6-9

Sacrifice and offering you did not desire— but my ears you have opened— burnt offerings and sin offerings you did not require. Then I said, “Here I am, I have come— it is written about me in the scroll. I desire to do your will, my God; your law is within my heart.” I proclaim your saving acts in the great assembly; I do not seal my lips, LORD, as you know.
