'Sinned' in the Bible

and David saith unto God, 'I have sinned exceedingly, in that I have done this thing; and now, cause to pass away, I pray Thee, the iniquity of Thy servant, for I have acted very foolishly.'

And David saith unto God, 'Did not I -- I say to number the people? Yea, I it is who have sinned, and done great evil: and these, the flock, what did they? O Jehovah, my God, let, I pray Thee, Thy hand be on me, and on the house of my father, and not on Thy people -- to be plagued.'
