Ecclesiastes 10:8

⁶ Folly is set in great dignity, and the rich sit in low place.

⁷ I have seen servants upon horses, and princes walking as servants upon the earth.

He that diggeth a pit shall fall into it; and whoso breaketh an hedge, a serpent shall bite him.

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

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

Do read the surrounding verses too, because the context often says more than a single verse.
