The phrase “two-edged sword” first entered the English language in William Tyndale’s 1525 translation of the New Testament Letter to the Hebrews: “For the word of God is quick, and mighty in operation, and sharper than any two-edged sword” (Hebrews 4:12). Though the term originally referred only to an extremely sharp weapon or a blade that could cut in either direction, it has become a common metaphor (along with the related “double-edged sword”) to describe an idea that can be dangerous in either outcome or direction.
