Proverbs 27:1-3

Amplified Bible, Classic Edition

27 Do not boast of [yourself and] tomorrow, for you know not what a day may bring forth.^(A)

² Let another man praise you, and not your own mouth; a stranger, and not your own lips.

³ Stone is heavy and sand weighty, but a fool’s [unreasoning] wrath is heavier and more intolerable than both of them.
