Luke 17:24

For just like the lightning flashes ¹  and lights up the sky from one side to the other, so will the Son of Man be in his day. ² 

Job 37:3,4; Zec 9:14; Mal 3:1,2; Mal 4:1,2; Mt 24:27; Mt 24:30; Mt 25:31; Mt 26:64; 1Th 5:2; 2Th 2:2,8; Jas 5:8; 2Pe 3:10

¹ sn The Son of Man’s coming in power will be sudden and obvious like lightning. No one will need to point it out.

² tc Some very important mss (Ì⁷⁵ B D it sa) lack the words ἐν τῇ ἡμέρα αὐτοῦ (en th Jhmera autou, “in his day”), but the words are included in א A L W Θ Ψ Ë^1,13 Ï lat sy bo. On the one hand, the shorter reading is impressive because it has some of the best Alexandrian and Western witnesses in support; on the other hand, the expression ἐν τῇ ἡμέρα αὐτοῦ is unusual (found nowhere else in the NT), and may be considered the harder reading. A decision is difficult, but it is probably best to retain the words. NA²⁷ rightly has the words in brackets, expressing doubt as to their authenticity.
