Proverbs 27:4

2 Let another man praise you, and not your own mouth; a stranger, and not your own lips.

3 A stone heavy, and the sand weighty; but a fool's wrath heavier than them both.

4 Wrath cruel, and anger outrageous; but who able to stand before envy?

5 Open rebuke better than secret love.

6 Faithful the wounds of a friend; but the kisses of an enemy deceitful.
