Luke 13:2

13:2 He ¹  answered them, “Do you think these Galileans were worse sinners ²  than all the other Galileans, because they suffered these things?

Luke 17:24

17:24 For just like the lightning flashes ³  and lights up the sky from one side to the other, so will the Son of Man be in his day. ⁴ 

[13:2]  ¹ tn Grk “And he.” Here καί (kai) has been translated as “now” to indicate the transition to a new topic.

[13:2]  ² sn Jesus did not want his hearers to think that tragedy was necessarily a judgment on these people because they were worse sinners.

[17:24]  ³ 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]  ⁴ 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.
