Matthew 24:17-21

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.

For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will again.
