Matthew 24:16-20
24:16 then those in Judea must flee to the mountains.
24:17 The one on the roof must not come down to take anything out of his house,
24:18 and the one in the field must not turn back to get his cloak.
24:19 Woe to those who are pregnant and to those who are nursing their babies in those days!
24:20 Pray that your flight may not be in winter or on a Sabbath.
