Darby
9 Now I rejoice, not that ye have been grieved, but that ye have been grieved to repentance; for ye have been grieved according to God, that in nothing ye might be injured by us.
KJV
9 Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing.
