Ecclesiastes 10:8-11

New King James Version

^8 (A)He who digs a pit will fall into it,
And whoever breaks through a wall will be bitten by a serpent.
⁹ He who quarries stones may be hurt by them,
And he who splits wood may be endangered by it.
¹⁰ If the ax is dull,
And one does not sharpen the edge,
Then he must use more strength;
But wisdom ^[a]brings success.

¹¹ A serpent may bite ^(B)when it is not charmed;
The ^[b]babbler is no different.
