Psalm 40:6-10 New Revised Standard Version (NRSV)
6 Sacrifice and offering you do not desire,
but you have given me an open ear.
Burnt offering and sin offering
you have not required.
7 Then I said, “Here I am;
in the scroll of the book it is written of me.
8 I delight to do your will, O my God;
your law is within my heart.”
9 I have told the glad news of deliverance
in the great congregation;
see, I have not restrained my lips,
as you know, O Lord.
10 I have not hidden your saving help within my heart,
I have spoken of your faithfulness and your salvation;
I have not concealed your steadfast love and your faithfulness
from the great congregation.
