Ecclesiastes 10:8-10

21st Century King James Version

⁸ He that diggeth a pit shall fall into it; and whoso breaketh through a hedge, a serpent shall bite him.

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

¹⁰ If the ax be blunt and one does not whet the edge, then must he put to it more strength; but wisdom is profitable to direct him.
