That it may not be
προσεύχεσθε δὲ ἵνα μὴ γένηται χειμῶνος·
There is something similar in Matthew, chapter 24:20, but not in Luke. Mark indicated that Jesus said that they should pray (προσεύχεσθε δὲ) that their flight would not happen in the winter (ἵνα μὴ γένηται χειμῶνος). Matthew added the comment about the Sabbath, since Matthew considered himself and the followers of Jesus as faithful Jews. However, Mark made no mention about fleeing on the Sabbath.
