'Sinned' in the Bible

As for me, I said, “O Lord, be gracious to me;Heal my soul, for I have sinned against You.”

Against You, You only, I have sinnedAnd done what is evil in Your sight,So that You are justified when You speakAnd blameless when You judge.

In spite of all this they still sinnedAnd did not believe in His wonderful works.

We have sinned like our fathers,We have committed iniquity, we have behaved wickedly.
