Mark 13:15-19

Whoever is on the housetop must not go down, nor go in to get anything 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 it will not happen in winter.

For those days will be such a time of tribulation as has not occurred since the beginning of the creation which God created until now, and never will again.
