Proverbs 27:1-4

¹Do not boast about tomorrow, for you do not know what a day may bring.

²Let someone else praise you and not your own mouth; a stranger and not your own lips.

³Consider the heaviness of a stone and the weight of sand— the provocation of a fool is heavier than both.

⁴There is the cruelty of rage and the flood of anger, but who is able to stand before jealousy?
