Mark 13:14-23 (Tuesday after the Publican and the Pharisee)
The Lord said: "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; let him who is on the housetop not go down, nor enter his house, to take anything away; and let him who is in the field not turn back to take his mantle. And alas for those who are with child and for those who give suck in those days! Pray that it may not happen in winter. For 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. And if the Lord had not shortened the days, no human being would be saved; but for the sake of the elect, whom he chose, he shortened the days. And then if any one says to you, 'Look, here is the Christ!' or 'Look, there he is!' do not believe it. False Christs and false prophets will arise and show signs and wonders, to lead astray, if possible, the elect. But take heed; I have told you all things beforehand.
