Psalms 40:8
King James Version
“I delight to do thy will, O my God: yea, thy law within my heart.”
Context
5Many, O LORD my God, thy wonderful works thou hast done, and thy thoughts to us-ward: they cannot be reckoned up in order unto thee: I would declare and speak 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 written of me,
8I delight to do thy will, O my God: yea, thy law within my heart.
9I have preached righteousness in the great congregation: lo, I have not refrained my lips, O LORD, thou knowest.
10I have not hid thy righteousness within my heart; I have declared thy faithfulness and thy salvation: I have not concealed thy lovingkindness and thy truth from the great congregation.
11Withhold not thou thy tender mercies from me, O LORD: let thy lovingkindness and thy truth continually preserve me.
