'Sinned' in the Bible

Then David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has taken away your sin; 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 go down to meet my lord the king.”

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

Then David spoke to the Lord when he saw the angel who was striking down the people, and said, “Behold, it is I who have sinned, and it is I who have done wrong; but these sheep, what have they done? Please let Your hand be against me and against my father’s house.”
