I waited, waited for the LORD

Psalms 40,2.4.7-8.10.11.

I waited, waited for the LORD; who bent down and heard my cry,
And put a new song in my mouth, a hymn to our God. Many shall look on in awe and they shall trust in the LORD.
sacrifice and offering you do not want; but ears open to obedience you gave me. Holocausts and sin-offerings you do not require;
so I said, "Here I am; your commands for me are written in the scroll.
I announced your deed to a great assembly; I did not restrain my lips; you, LORD, are my witness.
Your deed I did not hide within my heart; your loyal deliverance I have proclaimed. I made no secret of your enduring kindness to a great assembly.
