(Before It's News)
6 Sacrifice and offering thou dost not desire; but thou hast given me an open ear. Burnt offering and sin offering thou hast not required.
7 Then I said, “Lo, I come; in the roll of the book it is written of me;
8 I delight to do thy will, O my God; thy law is within my heart.”
9 I have told the glad news of deliverance in the great congregation; lo, I have not restrained my lips, as thou knowest, O LORD.
10 I have not hid thy saving help within my heart, I have spoken of thy faithfulness and thy salvation; I have not concealed thy steadfast love and thy faithfulness from the great congregation.
