'Sinned' in the Bible

David said to God, "I have sinned greatly, in that I have done this thing. But now, put away, I beg you, the iniquity of your servant; for I have done very foolishly."

David said to God, "Isn't it I who commanded the people to be numbered? It is even I who have sinned and done very wickedly; but these sheep, what have they done? Please let your hand, O Yahweh my God, be against me, and against my father's house; but not against your people, that they should be plagued."
