This unique compound describes Scripture as 'God-breathed'—not merely inspired by God but breathed out from him. It combines θεός (God) with πνέω (to breathe), creating the powerful image of God's breath producing Scripture. Paul uses it in his classic statement about Scripture's nature and purpose in 2 Timothy. The term emphasizes divine origin rather than human composition, though it doesn't exclude human authorship. It's God's exhaled word, carrying his authority and power. This hapax (appearing only once) has profoundly shaped Christian understanding of biblical inspiration.
