Ecclesiastes 10:9

American Standard Version 2015

Whoso heweth out stones shall be hurt therewith; {\i and} he that cleaveth wood is endangered thereby.

See the chapter Copy

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

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.
