32 The lips of the righteous know how to obtain favor; but the mouth of the wicked speaketh perverseness.
2 He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart;
3 That uttereth no calumny with his tongue, that doth no evil to his neighbor, and bringeth no reproach on his fellowman;
24 Remove from thee frowardness of mouth; and perverseness of lips put away far from thee.
13 (34:14) Guard thy tongue from evil, and thy lips from speaking deceit.
5 Every saying of God is purified: he is a shield unto those that put their trust in him.
30 The way of truth have I chosen: thy ordinances have I set before me.
5 Lead me in thy truth, and teach me; for thou art the God of my salvation: on thee do I wait all the day.
4 For the word of the Lord is upright; and all his works are done in truth.
