Psalm 40:7 KJV

5Many, O LORD my God, are thy wonderful works which thou hast done, and thy thoughts which are to us-ward: they cannot be reckoned up in order unto thee: if I would declare and speak of them, they are more than can be numbered.

6Sacrifice and offering thou didst not desire; mine ears hast thou opened: burnt offering and sin offering hast thou not required.

7Then said I, Lo, I come: in the volume of the book it is written of me,

8I delight to do thy will, O my God: yea, thy law is within my heart.

9I have preached righteousness in the great congregation: lo, I have not refrained my lips, O LORD, thou knowest.
