Ecclesiastes 10:9-11

New American Standard Bible

⁹ One who quarries stones may be hurt by them, and one who splits logs may be endangered by them. ¹⁰ If the ^[a]axe is dull and he does not sharpen its ^[b]edge, then he must exert more strength. Wisdom has the advantage of bringing success. ¹¹ If the serpent bites ^[c](A)before being charmed, there is no benefit for the charmer.
