Ecclesiastes 10:6-11
English Standard Version
Chapter 10
6folly is set in many high places, and the rich sit in a low place. 7I have seen slaves on horses, and princes walking on the ground like slaves.
8He who digs a pit will fall into it, and a serpent will bite him who breaks through a wall.
9 He who quarries stones is hurt by them, and he who splits logs is endangered by them.
10If the iron is blunt, and one does not sharpen the edge, he must use more strength, but wisdom helps one to succeed.
11If the serpent bites before it is charmed, there is no advantage to the charmer.
