Ecclesiastes 10:8-11

8 He who adigs a pit will fall into it,
and ba serpent will bite him who breaks through a wall.
9 cHe who quarries stones is hurt by them,
and he who dsplits 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.
Or  wisdom is an advantage for success

11If the serpent bites before it is fcharmed,
there is no advantage to the charmer.
