Matthew 24:16-20

then those who are in Judea must flee to the mountains.

Whoever is on the housetop must not go down to get things out of his house.

And whoever is in the field must not turn back to get his cloak.

But woe to those women who are pregnant, and to those who are nursing babies in those days!

Moreover, pray that when you flee, it will not be in the winter, or on a Sabbath.
