9 With his mouth the evil man sends destruction on his neighbour; but through knowledge the upright are taken out of trouble.
28 A man of twisted purposes is a cause of fighting everywhere: and he who says evil secretly makes trouble between friends.
2 He who goes on his way uprightly, doing righteousness, and saying what is true in his heart;
3 Whose tongue is not false, who does no evil to his friend, and does not take away the good name of his neighbour;
29 Let no evil talk come out of your mouth, but only what is good for giving necessary teaching, and for grace to those who give ear.
18 Hate is covered up by the lips of the upright man, but he who lets out evil about another is foolish.
11 Happy are you when men give you a bad name, and are cruel to you, and say all evil things against you falsely, because of me.
13 He who goes about talking of others makes secrets public, but the true-hearted man keeps things covered.
