'Sinned' in the Bible

and they have turned it back unto their heart in the land whither they have been taken captive, and have turned back, and made supplication unto Thee in the land of their captivity, saying, We have sinned, we have done perversely, and have done wickedly;

then Thou hast heard from the heavens, from the settled place of Thy dwelling, their prayer and their supplications, and hast maintained their cause, and forgiven Thy people who have sinned against Thee.
