Finally upon the bird of abominations desolation, to the point of ending and cutting off, shall be poured drop by drop upon devastation. Dan. 9:27.

In Matthew's gospel the Lord says:

Then many false prophets shall arise and lead many astray. When therefore you see the abomination of desolation predicted by the prophet Daniel standing in the holy place, let him who reads take due notice. Matt. 24:[11,] 15.

Later in the same chapter:

Then there shall be great affliction, such as never was from the beginning of the world until now, nor ever will be. Matt. 24:21.

This affliction and the abomination are dealt with in seven chapters of Revelation. These are what is meant by the black horse and the pale horse which came out of the book, when the Lamb opened its seals (Rev. 6:5-8); and by the beast coming up out of the abyss, which made war on the two witnesses, and killed them (11:7ff.); as by the dragon which stood in front of the woman who was about to give birth, to devour her child, and pursued her into the desert, and there ejected water from its mouth like a river, to drown her (chapter 12); also by the beasts of the dragon, one from the sea, the other from the land (chapter 13); also by the three spirits like frogs, who came out of the mouth of the dragon and the mouth of the beast and the mouth of the false prophet (16:13); moreover by the fact that after the seven angels had poured out the bowls of the wrath of God, in which were the seven last plagues, upon the earth, the sea, the springs and streams, the sun, the throne of the beast, the Euphrates and finally the air, a great earthquake took place such as had never occurred since the creation of man (chapter 16). The earthquake means the overthrow of the church, the result of falsities and falsifications of truth, much as is meant by the great affliction such as never has been since the beginning of the world (Matt. 24:21). The following passage has a similar meaning:

The angel put in his sickle and reaped the grape-harvest of the earth, and threw it into the great winepress of the wrath of God; and the winepress was trodden, and blood came out up to the bridles of the horses at a distance of one thousand six hundred stades*. Rev. 14:19, 20.

Blood means falsified truth. There are many more such passages in those seven chapters.

*The stade was an ancient measure of length, roughly 170 metres; the distance is approximately 170 miles.
