1 Boast not yourself of tomorrow; for you know not what a day may bring forth.
2 Let another man praise you, and not your own mouth; a stranger, and not your own lips.
3 A stone is heavy, and the sand weighty; but a fool's wrath is heavier than them both.
4 Wrath is cruel, and anger is outrageous; but which is able to stand before jealousy?
