Proverbs 12:18; Proverbs 25:18; Proverbs 30:14

18 There is that speaketh like the piercings of a sword: but the tongue of the wise is health.

18 A man that beareth false witness against his neighbour is a maul, and a sword, and a sharp arrow.

14 There is a generation, whose teeth are as swords, and their jaw teeth as knives, to devour the poor from off the earth, and the needy from among men.
