See the Seven in BOLD Above. Where else are Seven Beast Heads Mentioned?
I will explain what I meant.
There are the 7 heads on the beast, yes, in all three chapters 17, 12, 13. The little horn person being one of them, the 7th.
However, in Revelation 13... it says the beast when coming out of the sea has the mouth of a lion. Where is that lion's mouth?
In his rear end? Well, metaphorically we sometimes say "speaking out of his rear end"..
.... but I don't think we can apply that to the beast John saw. There has to be a main head on the beast which is not one of the seven heads.
That main head is the one with the lion's mouth.
The little horn person does the big talk when he first shows up among the ten kings, out of the EU, imo.
But regardless, he talks big. Then later, after he becomes the King of Israel, the Antichrist. 3 years 3 months into his reign, he goes rogue, goes into the temple, sits, claims to be God. Now that is really big blasphemous talk. God has him killed. The mortally wounded head.
Who, the person comes back to life - healed. Which that mortally wounded/healed head only appears in Revelation 13 with 42 months left. So we know it takes place right around that time, slightly before.
So having recovered - the 7th king continues the short space as the beast (in Revelation 13) which when he is speaking for those 42 months, against God and them in heaven, it is from the mouth of the lion - which belongs to the main head on the beast. Which the person has become that "first beast" in Revelation 13 coming out of the sea.
Now do you see what I talking about clarifying which head? There are 7 heads on the beast - BUT the beast itself has it's main head, that with a mouth of a lion.
