Proverbs 27:17 is a verse from the Book of Proverbs in the Hebrew Bible, which is part of the Wisdom Literature in the Old Testament. The verse is often translated as "Iron sharpens iron, and one man sharpens the countenance of his friend" in the English Standard Version (ESV). In Hebrew, the verse is written as "ברזל ברזל יחריב פני חרב וראי יחריב פני רעיה" (Barzel barzel yachreiv p'nei cherev, ve-raya yachreiv p'nei rayahu). This proverb emphasizes the importance of mutual growth and improvement through interpersonal relationships, particularly those that involve challenge and constructive criticism. The metaphor of iron sharpening iron suggests that, just as a blade is honed through friction against another piece of iron, individuals can refine and improve their character, skills, and understanding through meaningful interactions with others. The verse is often interpreted in the context of friendship, mentorship, and community, highlighting the value of relationships that foster personal and spiritual growth. Translations of this verse in other languages include "El hierro se aguza con el hierro, y el hombre con el trato de su amigo" in Spanish, and "Le fer aiguise le fer, et l'homme aiguise le visage de son ami" in French.
