phengos denotes visible illumination, shown in a lamp’s brightness and in the light the moon gives.

The occurrences show visible illumination: in Luke 11:33 it is what a lamp on a stand enables entrants to see, while Mark 13:24 and Matthew 24:29 place it in the moon’s failure to give light after the sun is darkened.

   All three occurrences use the accusative singular neuter form in clauses concerning what is seen or given as light. In Luke 11:33 the APB renders a lamp set on a lampstand so that those entering may see “the brightness”; in Mark 13:24 and Matthew 24:29 it renders the moon as not giving its light or brightness when the sun is darkened.

In the Anselm Project Bible: The APB presents the term with “brightness” in Luke 11:33 and Matthew 24:29, and with “light” in Mark 13:24. These renderings confirm the clauses’ illumination imagery rather than establish separate senses.
