Sirach 28:20LXX

18It hath cut in pieces the forces of people, and undone strong nations.

19The tongue of a third person hath cast out valiant women, and deprived them of their labours.

20He that hearkeneth to it, shall never have rest, neither shall he have a friend in whom he may repose.

21The stroke of a whip maketh a blue mark: but the stroke of the tongue will break the bones.

22Many have fallen by the edge of the sword, but not so many as have perished by their own tongue.
