Markus 13:18

13:18 Pray that it may not be in winter.

Markus 12:23

12:23 In the resurrection, when they rise again, ¹  whose wife will she be? For all seven had married her.” ² 

[12:23]  ¹ tc The words “when they rise again” are missing from several important witnesses (א B C D L W Δ Ψ 33 579 892 2427 pc c r¹ k sy^p co). They are included in A Θ Ë^1,(13) Ï lat sy^s,h. The strong external pedigree of the shorter reading gives one pause. Nevertheless, the Alexandrian and other mss most likely dropped the words from the text either to conform the wording to the parallel in Matt 22:28 or because “when they rise again” was redundant. But the inclusion of these words is thoroughly compatible with Mark’s usually pleonastic style (see TCGNT 93), and therefore most probably authentic to Mark’s Gospel.
