Ecclesiastes 10:8-10

American Standard Version

⁸ He that diggeth a pit shall fall into it; and whoso breaketh through a wall, a serpent shall bite him. ⁹ Whoso ^[a]heweth out stones shall be hurt therewith; and he that cleaveth wood is endangered thereby. ¹⁰ If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
