14"But when you see the desolating sacrilege set up where it ought not to be (let the reader understand), then let those who are in Judea flee to the mountains; 15let him who is on the housetop not go down, nor enter his house, to take anything away; 16and let him who is in the field not turn back to take his mantle. 17And alas for those who are with child and for those who give suck in those days! 18Pray that it may not happen in winter. 19For in those days there will be such tribulation as has not been from the beginning of the creation which God created until now, and never will be.
