Proverbs 27:1-5

27:1 Do not boast about tomorrow;

for you do not know what a day may bring forth.

27:2 Let another praise you, and not your own mouth;

someone else, and not your own lips.

27:3 A stone is heavy and sand is weighty,

but vexation by a fool is more burdensome than the two of them.

27:4 Wrath is cruel and anger is overwhelming,

but who can stand before jealousy?

27:5 Better is open rebuke

than hidden love.
