“The ten horns are ten kings who shall arise from this kingdom. And another shall rise after them; He shall be different from the first ones, and shall subdue three kings.” (Dan 7:24)
“The ten horns which you saw are ten kings who have received no kingdom as yet, but they receive authority for one hour as kings with the beast. (Rev 17:12)
