Psalms 40:8 ASV

⁶  Sacrifice and offering thou hast no delight in; Mine ears hast thou opened: Burnt-offering and sin-offering hast thou not required.

⁷  Then said I, Lo, I am come; In the roll of the book it is written of me:

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

⁹  I have proclaimed glad tidings of righteousness in the great assembly; Lo, I will not refrain my lips, O Jehovah, thou knowest.

¹⁰  I 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 assembly.
