The verb φλεγω (phlego) means to burn or shine like a fire. It's not used in the New Testament (the Septuagint uses it three times: Exodus 3:2, Isaiah 29:6, Joel 1:19). From this verb derives:
- The noun φλοξ (phlox), meaning a brightly burning fire or bright flame (Luke 16:24, Acts 7:30, 2 Thessalonians 1:8, Hebrews 1:7, Revelation 1:4, 2:18, and 19:12). This word denotes the flame object, and often occurs in tandem with πυρα (pura), meaning fire as concept (hence a "flame of fire"). From our noun in turn derives:
- The verb φλογιζω (phlogizo), meaning to set ablaze. This verb is used twice in James 3:6, where the tongue is said to set on fire the course of one's life, and is itself set on fire by Gehenna.
