Ecclesiastes 10:9-16

⁹Whoso removeth stones shall be hurt therewith; and he that cleaveth wood shall be endangered thereby.

¹⁰If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.

¹¹Surely the serpent will bite without enchantment; and a babbler is no better.

¹²The words of a wise man’s mouth are gracious; but the lips of a fool will swallow up himself.

¹³The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.

¹⁴A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?

¹⁵The labour of the foolish wearieth every one of them, because he knoweth not how to go to the city.

¹⁶Woe to thee, O land, when thy king is a child, and thy princes eat in the morning.
