Matthew 24:16-20

Then let them which be in Judaea flee into the mountains:

Let him which is on the housetop not come down to take any thing out of his house:

Neither let him which is in the field return back to take his clothes.

And woe unto them that are with child, and to them that give suck in those days!

But pray ye that your flight be not in the winter, neither on the sabbath day:
