The most wise prophet Daniel foresaw that these ten kings, that is, horns, would come from the Roman dominion. He said that they would rise in the last times, and that Antichrist would rise among them.
For this very reason it is said: "They have not yet received a kingdom, but they will receive authority as kings." Truly, "as kings," because of the fleeting and darkened character of their reign.
Then it is added: "They receive authority with the beast for one hour." Here Antichrist is called the beast. In the preceding chapters John also called him so: "And I saw another beast coming up out of the earth. He had two horns like a lamb" (Rev 13:11).
That one hour is appointed for them to rule either signifies the shortness of their reign, or else one year is meant figuratively.
