Proverbs 11:13, 18:8, 26:17, 17:4, 11:25, 22:11, 27:2
Whoever goes about slandering reveals secrets, but he who is trustworthy in spirit keeps a thing covered. … The words of a whisperer are like delicious morsels; they go down into the inner parts of the body. … Whoever meddles in a quarrel not his own is like one who takes a passing dog by the ears. … An evildoer listens to wicked lips, and a liar gives ear to a mischievous tongue. … Whoever brings blessing will be enriched, and one who waters will himself be watered. … He who loves purity of heart, and whose speech is gracious, will have the king as his friend. … Let another praise you, and not your own mouth; a stranger, and not your own lips.
