Brethren, concerning the coming of our Lord Jesus Christ and our assembling to meet him, we beg you not to be quickly shaken in mind or excited, either by spirit or by word, or by letter purporting to be from us, to the effect that the day of the Lord has come. Let no one deceive you in any way; for that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of perdition, who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God. Do you not remember that when I was still with you I told you this? And you know what is restraining him now so that he may be revealed in his time. For the mystery of lawlessness is already at work; only he who now restrains it will do so until he is out of the way. And then the lawless one will be revealed, and the Lord Jesus will slay him with the breath of his mouth and destroy him by his appearing and his coming. The coming of the lawless one by the activity of Satan will be with all power and with pretended signs and wonders, and with all wicked deception for those who are to perish, because they refused to love the truth and so be saved. Therefore God sends upon them a strong delusion, to make them believe what is false, so that all may be condemned who did not believe the truth but had pleasure in unrighteousness.

At that time, as some spoke to Jesus of the temple, how it was adorned with noble stones and offerings, he said, "As for these things, which you see, the days will come when there shall not be left here one stone upon another that will not be thrown down." And they asked him, "Teacher, when will this be, and what will be the sign when this is about to take place?" And he said, "Take heed that you are not led astray; for many will come in my name, saying, 'I am he!' and, 'The time is at hand!' Do not go after them. And when you hear of wars and tumults, do not be terrified; for this must first take place, but the end will not be at once."

Then he said to them, "Nation will rise against nation, and kingdom against kingdom; there will be great earthquakes, and in various places famines and pestilences; and there will be terrors and great signs from heaven.

But when you see Jerusalem surrounded by armies, then know that its desolation has come near. Then let those who are in Judea flee to the mountains, and let those who are inside the city depart, and let not those who are out in the country enter it; for these are days of vengeance, to fulfill all that is written. Alas for those who are with child and for those who give suck in those days! For great distress shall be upon the earth and wrath upon this people; they will fall by the edge of the sword, and be led captive among all nations; and Jerusalem will be trodden down by the Gentiles, until the times of the Gentiles are fulfilled."
