He even exalted himself as high as the Prince of the host; and by him the daily sacrifices were taken away, and the place of His sanctuary was cast down. Because of transgression, an army was given over to the horn to oppose the daily sacrifices; and he cast truth down to the ground. He did all this and prospered.
Then I heard a holy one speaking; and another holy one said to that certain one who was speaking, “How long will the vision be, concerning the daily sacrifices and the transgression of desolation, the giving of both the sanctuary and the host to be trampled underfoot?” And he said to me, “For two thousand three hundred days; then the sanctuary shall be cleansed.”
Then he shall confirm a covenant with many for one seven;
But in the middle of the seven
He shall bring an end to sacrifice and offering.
And on the wing of abominations shall be one who makes desolate,
Even until the consummation, which is determined,
Is poured out on the desolate.”
“And from the time that the daily sacrifice is taken away, and the abomination of desolation is set up, there shall be one thousand two hundred and ninety days. 12 Blessed is he who waits, and comes to the one thousand three hundred and thirty-five days.
“Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place” (whoever reads, let him understand), “then let those who are in Judea flee to the mountains.Let him who is on the housetop not go down to take anything out of his house.And let him who is in the field not go back to get his clothes. But woe to those who are pregnant and to those who are nursing babies in those days!And pray that your flight may not be in winter or on the Sabbath. For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be.And unless those days were shortened, no flesh would be saved; but for the elect’s sake those days will be shortened.
2 Thessalonians 2:1-4
Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
And he deceives those who dwell on the earth by those signs which he was granted to do in the sight of the beast, telling those who dwell on the earth to make an image to the beast who was wounded by the sword and lived. He was granted power to give breath to the image of the beast, that the image of the beast should both speak and cause as many as would not worship the image of the beast to be killed. He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name. Here is wisdom. Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666.
