An interrogative or exclamatory adjective asking 'how large?' or declaring 'how great!' Paul uses it for emphasis about physical size in Galatians 6:11—'See with what large letters I write to you with my own hand'—possibly referring to poor eyesight or simply emphasizing the personal nature of this final section. In Hebrews 7:4, it introduces the greatness of Melchizedek: 'Consider how great this man was' to whom even Abraham gave a tithe. The word measures magnitude, whether literal dimensions or metaphorical greatness.
