'Sinned' in the Bible

Then David said to Nathan, "I have sinned against Yahweh!" Nathan said to David, "Yahweh has also forgiven your sin; you shall not die.

For your servant knows that I have sinned; look, I have come this day [as the first] of all the house of Joseph to come down to meet my lord the king."

The heart of David struck him after he had counted the people, and David said to Yahweh, "I have sinned greatly in what I have done! So then, O Yahweh, please forgive the guilt of your servant because I have acted very foolishly."

David spoke to Yahweh when he saw the angel destroying among the people, and he said, "Look, I have sinned and I have done wrong, but these sheep, what did they do? Please let your hand be against me and against the house of my father."
