Psalms 40:6-9

Sacrifice and offering thou hast no delight in; Mine ears hast thou opened: Burnt-offering and sin-offering hast thou not required. Then said I, Lo, I am come; In the roll of the book it is written of me: I delight to do thy will, O my God; Yea, thy law is within my heart. I have proclaimed glad tidings of righteousness in the great assembly; Lo, I will not refrain my lips, O Jehovah, thou knowest.
