9 The hypocrite destroys his neighbor with his mouth, but the righteous shall be delivered through knowledge.
18 He who hides hatred is of lying lips. And he who utters a slander is a fool.
28 A perverse man scatters abroad strife, and a whisperer separates chief friends.
29 Let no corrupt speech go out of your mouth, rather if there is any good word for edification of a need, so that it may give grace to those who hear.
2 He who walks uprightly, and works righteousness, and speaks truth in his heart,
3 he who does no slander with his tongue, nor does evil to his friend, nor takes up a reproach against his neighbor,
11 Blessed are ye when they revile you, and persecute you, and say every evil word, being deceitful against you because of me.
13 He who goes around as a tale-bearer reveals secrets, but he who is of a faithful spirit conceals a matter.
