Proverbs 27:1-6

Don’t brag about tomorrow, since you don’t know what the day will bring. Let someone else praise you, not your own mouth— a stranger, not your own lips. A stone is heavy and sand is weighty, but the resentment caused by a fool is even heavier. Anger is cruel, and wrath is like a flood, but jealousy is even more dangerous. An open rebuke is better than hidden love! Wounds from a sincere friend are better than many kisses from an enemy.
