Proverbs 27:1-5

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

Let another praise you, and not your own mouth; A stranger, and not your own lips.

A stone is heavy and the sand weighty, But the provocation of a fool is heavier than both of them.

Wrath is fierce and anger is a flood, But who can stand before jealousy?

Better is open rebuke Than love that is concealed.
