Proverbs 27:2-6

Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips.

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

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

Open rebuke is better than secret love.

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