King James wording
King James Version
For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day.THE KEY
The Son of Man’s day is as unmistakable as lightning that flashes across the whole sky.
THE MEANING
The Son of Man’s day is not something you locate by following a whispered claim of “Lo here” or “Lo there.” Like lightning spanning the sky, it is visible across the whole field. Its arrival carries its own evidence.
WHAT THIS UNDOES
The verse undoes the belief that you must follow someone to a hidden or local appearance of the Son of Man.
THE ROOT
ἀστραπή
astrapē
GROWS FROM
ἀστραπ-
astrap-
flash; lightning
“flashing” in this verse is astrapē. The Greek names lightning with ἀστραπή and describes it with ἀστράπτουσα, a verb from the same word family: the lightning is “lightning-ing.” The repeated root makes the image self-evident, the flash itself makes the Son of Man’s day known across the sky.
ALSO GROWS
astraptō: to flash like lightning
ἀστράπτω
This is the verb family behind “lighteneth,” linking the lightning to its flashing action.
astrapaios: lightning-like
ἀστραπαῖος
This related form carries the lightning image into a description of something that appears like a flash.
λάμπει
lampei
GROWS FROM
λαμπ- (lamp-, from λάμπω, lampō)
shine; give light
The verse moves from the lightning’s flash to λάμπει, “shines,” describing light extending from one side of the sky to the other. The image is not merely suddenness; it is radiance that fills the visible span.
ALSO GROWS
lampas: lamp; torch
λαμπάς
A lamp gives off light that can be seen, echoing the verse’s emphasis on visible radiance.
lampros: bright; radiant
λαμπρός
This related form names the brightness that makes an appearance conspicuous.
THE PATTERN
The manifestation of God’s action is described as reaching beyond a hidden place into the full field of sight.
He straightens it under all the heavens, and his light upon the wings of the earth.Look, he comes with the clouds, and every eye will see him, and those who pierced him. All the tribes of the earth will beat their breasts over him. Yes, amen.THE THREAD
For as the lightning comes out from the east and shines all the way to the west, so is the presence of the Son of Man.Matthew repeats the Greek word ἀστραπή (astrapē), “lightning,” for the same image. Its east-to-west span opens Luke’s “one part” to “the other part” as a picture of a coming that is openly seen.
