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