'Sinned' in the Bible

David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has allowed your sin to pass [without further punishment]; you shall not die.

For your servant knows that I have sinned; therefore, behold, I have come today, the first of all the house of Joseph to come down to meet my lord the king.”

But David’s heart (conscience) troubled him after he had counted the people. David said to the Lord, “I have sinned greatly in what I have done. But now, O Lord, please take away the sin of Your servant, for I have acted very foolishly.”

When David saw the angel who was striking down the people, he spoke to the Lord and said, “Behold, I [alone] am the one who has sinned and done wrong; but these sheep (people of Israel), what have they done [to deserve this]? Please let Your hand be [only] against me and my father’s house (family).”
