Ecclesiastes 10:8

⁶ Folly is appointed to great heights, but the rich sit in lowly positions.

⁷ I have seen slaves on horseback, while princes go on foot like slaves.

He who digs a pit may fall into it, and he who breaches a wall may be bitten by a snake.

⁹ The one who quarries stones may be injured by them, and he who splits logs endangers himself.

¹⁰ If the axe is dull and the blade unsharpened, more strength must be exerted, but skill produces success.

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