 | As iron sharpens iron, so one man sharpens another. |
 | Iron sharpeneth iron; so a man sharpeneth the countenance of his friend. |
 | Iron sharpens iron, So one man sharpens another. |
| Proverbs 27:17 |
Commentary
A famous proverb, this verse may also be translated as applying to the will: "Let iron sharpen iron, and so let a person sharpen his friend." The idea is that people grow from interaction with one another.

Did you know?It takes iron to sharpen iron. Sharpening a knife requires iron at least as hard as the knife. Once sharpened, a knife is bright, sharp, and ready for much more productive service.
