9 An hypocrite with his mouth destroyeth his neighbour: but through knowledge shall the just be delivered.
28 A froward man soweth strife: and a whisperer separateth chief friends.
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
18 He that hideth hatred with lying lips, and he that uttereth a slander, is a fool.
2 He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart.
3 He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour.
11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
13 A talebearer revealeth secrets: but he that is of a faithful spirit concealeth the matter.
