Luke 17:24

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 

Luke 11:36

11:36 If ³  then ⁴  your whole body is full of light, with no part in the dark, ⁵  it will be as full of light as when the light of a lamp shines on you.” ⁶ 

[17:24]  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.

[17:24]  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.

[11:36]  ³ tn This is a first class condition in the Greek text, so the example ends on a hopeful, positive note.

[11:36]  ⁴ tn Grk “Therefore”; the same conjunction as at the beginning of v. 35, but since it indicates a further inference or conclusion, it has been translated “then” here.

[11:36]  ⁵ tn Grk “not having any part dark.”

[11:36]  ⁶ tn Grk “it will be completely illumined as when a lamp illumines you with its rays.”
