Ecclesiastes 10:7-10

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

⁸He that digs a pit shall fall into it; and him that breaks down a hedge a serpent shall bite.

⁹He that removes stones shall be troubled thereby; he that cleaves wood shall be endangered thereby.

¹⁰If the axe-head should fall off, then the man troubles his countenance, and he must put forth more strength: and in that case skill is of no advantage to a man.
