Refers to a massive, overwhelming inundation of water. In the New Testament this word appears exclusively in connection with the Genesis flood narrative, the archetypal divine judgment through water. Jesus cites the flood as a warning about the sudden, unexpected nature of the coming of the Son of Man (Matt 24:38-39; Luke 17:27), and Peter recalls it as a precedent for God's judgment on the ungodly (2 Pet 2:5). Every major translation tradition -- Spanish 'diluvio,' French 'deluge,' German 'Flut' -- uses its most dramatic flood vocabulary, reflecting the catastrophic scale implied by the Greek.
