And the ten horns are ten kings who will rise from this kingdom. After them another king, different from the earlier ones, will rise and subdue three kings.

Revelation 17:12
The ten horns you saw are ten kings who have not yet received a kingdom, but will receive one hour of authority as kings, along with the beast.

Daniel 7:7
After this, as I watched in my vision in the night, suddenly a fourth beast appeared, and it was terrifying--dreadful and extremely strong--with large iron teeth. It devoured and crushed; then it trampled underfoot whatever was left. It was different from all the beasts before it, and it had ten horns.

Daniel 7:23
This is what he said: 'The fourth beast is a fourth kingdom that will appear on the earth, different from all the other kingdoms, and it will devour the whole earth, trample it down, and crush it.

And the ten horns out of this kingdom are ten kings that shall arise: and another shall rise after them; and he shall be diverse from the first, and he shall subdue three kings.
