Spell out "great tribulation" and don't abbreviate, leaving out the word "great" . It is misleading to say "the trib".
No, it is not.
Revelation 12:17 is about the persecution of the Jews, who will have turned to Jesus in Revelation 12:10, bur who did not flee to the mountains in a timely manner, and thus become subject to persecution by Satan.
Mountains do not have crowns, kings do.
Doesn't matter in symbolic language. There is no 7 headed dragon or beast.
The heads are not the rulers. The horns are the rulers and the heads are WHERE they rule. This is just like Pagan Rome where Caesar (one of many antichrists) ruled over ten states with their rulers (the ten horns) and these ten states (mini-kingdoms) were LOCATED on 7 hills (the 7 heads/mountains).
Obviously the 7 hills weren't an additional 7 leaders in Rome anymore than they are 7 more Kings in Rev 13, 17.
Here's the basic issue:
Some translations are based on a manuscript, and some are based on a different manuscript. The manuscripts differ in various ways and this is one of them:
Rev 17:9 And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth.
Rev 17:10
And there are seven kings: five are fallen, and one is, and the other is not yet come; and when he cometh, he must continue a short space.
The KJV has the 7 heads/mountains as separate as the 7 kings while other translations have the 7 heads/mountains as also being the 7 kings:
Rev 17:9 This calls for a mind with wisdom: the seven heads are seven mountains on which the woman is seated;
Rev 17:10
they are also seven kings, five of whom have fallen, one is, the other has not yet come, and when he does come he must remain only a little while.
Both cannot be correct but there is an easy way to figure out which one is right and which isn't.
Rev 13:1 And I stood upon the sand of the sea, and saw a beast rise up out of the sea,
having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
"having seven heads" means the beast possess all 7 heads. If the manuscripts the ESV is based upon are right then the beast would have one head since it says 6 of the heads would have fallen (no longer exist) by the time of the 7th king/head. The fact that the beast has all 7 heads, and none of the heads had fallen means the ESV version is simply wrong. Furthermore, Rev 13 tells us one head was wounded and then healed so instead of 6 heads supposedly falling before the arrival of the 7th head, all the heads are perfectly intact and one even survives a serious wound and does not fall.
The manuscripts the KJV is based upon are correct because they accurately keep
the intact and unfallen 7 heads of the Rev 13:1 beast separate from the completely different information about previous kings which were successive and fell one by one until there was a 7th that was standing alone. These 7 kings are the same as the 4 successive beasts in Daniel. Only one existed at a time with the previous falling away. The 4th being equal to the 7th king (who has a beast-kingdom of course) of Rev 17.
Rev 17:9 This calls for a mind with wisdom:
the seven heads are seven mountains on which the woman is seated;
The 7 heads of the beast are said to be mountains and those are areas of land where kingdoms exist. The only things of the beast which represent kings are the horns:
Rev 17:12 And
the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.
So, 7 heads are 7 mountains, not kings. The ten horns are the kings of the beast and of course there are 10, not 7 and they are kings for the entire "one hour" the beast reigns over the world. None of the horns or mountains fall leaving others to stand. When it's time for any of the beast to fall, they all fall at the same time being defeated by Christ at Armageddon.
