'Sinned' in the Bible

Then David exclaimed to Nathan, "I have sinned against the Lord!" Nathan replied to David, "Yes, and the Lord has forgiven your sin. You are not going to die.

For I, your servant, know that I sinned, and I have come today as the first of all the house of Joseph to come down to meet my lord the king."

David felt guilty after he had numbered the army. David said to the Lord, "I have sinned greatly by doing this! Now, O Lord, please remove the guilt of your servant, for I have acted very foolishly."

When he saw the angel who was destroying the people, David said to the Lord, "Look, it is I who have sinned and done this evil thing! As for these sheep -- what have they done? Attack me and my family."
