Ecclesiastes 10:5-11

[5] There is an evil which I have seen under the sun, as it were an error proceeding from the ruler:
[6] folly is set in many high places, and the rich sit in a low place.
[7] I have seen slaves on horses, and princes walking on foot like slaves.
[8] He 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.
[10] If the iron is blunt, and one does not whet the edge,
he must put forth more strength;
but wisdom helps one to succeed.
[11] If the serpent bites before it is charmed,
there is no advantage in a charmer.
