"He will pitch the tents of his royal pavilion between the seas and the beautiful Holy Mountain; yet he will come to his end, and no one will help him.” (v.45)
Here in chapter 12, Daniel lays out details of the battles which take place before Armageddon, along with the defeat of the anti-christ and his rule. During the great tribulation, the Antichrist will be attacked in a pincer movement from both the north and the south, yet he will be successful, sweeping through like a flood (v.40).
He will also invade Israel, the beautiful land, ignoring some nations that are in alliance with him but conquering others, including Egypt, Libya, and Sudan (the Cushites) (vv.41-43). Then, reports of nations from the east and the north coming to attack will both terrify and infuriate him, leading him to pursue a course of genocidal warfare against his enemies, especially many of the Jewish people (v.44; Zech 13:8-9).
The Antichrist will then establish his military capital in Israel, pitching his royal tents between the Mediterranean Sea and the city of Jerusalem, situated on the beautiful holy mountain (v.45a). There the nations of the earth will gather (Zech 14:2) at Mount Megiddo to begin the campaign of Armageddon (Rev 16:13-16).
At that time, when the nation of Israel calls on the Messiah, Jesus will return (Mt 23:37-39) to deliver them, and the Antichrist will meet his end, with no one to help him (v.45b).
The Truth: “Then I saw the beast and the kings of the earth and their armies gathered together to wage war against the rider on the horse and his army. But the beast (anti-christ) was captured, and with it the false prophet who had performed the signs on its behalf. With these signs he had deluded those who had received the mark of the beast and worshiped its image. The two of them were thrown alive into the fiery lake of burning sulfur. The rest were killed with the sword coming out of the mouth of the rider on the horse, and all the birds gorged themselves on their flesh.” (Revelation 19:19-21)
