Mark 13:14-19

But when ye see the abomination of desolation standing where he ought not (let him that readeth understand), then let them that are in Judæa flee unto the mountains: and let him that is on the housetop not go down, nor enter in, to take anything out of his house: and let him that is in the field not return back to take his cloak. But woe unto them that are with child and to them that give suck in those days! And pray ye that it be not in the winter. For those days shall be tribulation, such as there hath not been the like from the beginning of the creation which God created until now, and never shall be.
