Ecclesiastes 10:8-10

Revised Geneva Translation

⁸ He who digs a pit shall fall into it. And he who breaks through a hedge will be bitten by a serpent.

⁹ He who removes stones shall hurt himself with them. He who cuts wood shall be in danger from it.

¹⁰ If the iron is blunt, and one has not sharpened the edge, he must then put more strength to it. But wisdom is the excellence to direct a thing.
