Mark 13:16 KJV

But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,) then let them that be in Judæa flee to the mountains:

And let him that is on the housetop not go down into the house, neither enter therein, to take any thing out of his house:

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

And pray ye that your flight be not in the winter.
