'Guilty' in the Bible

The woman said, "Why have you devised something like this against God's people? When the king speaks in this fashion, he makes himself guilty, for the king has not brought back the one he has banished.

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."
