Let the reader notice that our friend ewq1938 here completely ignores the context of Revelation 19:11-21, which obviously has to do with Christ destroying His enemies rather than ruling over them.
That's wrong. It is Amillennialism that claims the ruling happens during Armageddon. Since RULE is in the future tense, we know the RULING is something that happens AFTER Armageddon. This will be ignored because Amillennialism has no answer for the verb tense.
And he also fails to look at the original prophecy from Psalm 2 which also clearly has the context of Christ breaking/destroying His enemies rather than ruling over them the way ewq1938 erroneously thinks He will.
There is no "original" prophecy. Psalm 2 is NOT speaking of Armageddon. Ruling is also not mentioned. This is a diversion to make people not pay attention to Revelation 19 and it's FUTURE ruling over the nations after Armageddon.
It is also not about killing all the enemies but breaking up their kingdoms and power to be ruled over. Even in the Psalm it speaks of this:
Psa 2:8 Ask of me, and
I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.
Psa 2:9 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter's vessel.
Therefore breaking them with a rod of iron is not killing them.
The notion of breaking a nation or kingdom up so it is powerless is nothing new in scripture:
Dan 2:44 And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but
it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
Dan 2:45 Forasmuch as thou sawest that the stone was cut out of the mountain without hands, and that it brake in pieces the iron, the brass, the clay, the silver, and the gold; the great God hath made known to the king what shall come to pass hereafter: and the dream is certain, and the interpretation thereof sure.
The kingdom of God which Christ rules will break up the existing kingdoms of the nations leaving the people powerless to rebel. This is when the reign of the rod of iron over these nations takes place for a thousand years.
There is another use of a vessel being destroyed and it is not about killing people but breaking up an organization of people who rebel against God:
Isa 30:12 Wherefore thus saith the Holy One of Israel, Because ye despise this word, and trust in oppression and perverseness, and stay thereon:
Isa 30:13 Therefore this iniquity shall be to you as a breach ready to fall, swelling out in a high wall, whose breaking cometh suddenly at an instant.
Isa 30:14 And
he shall break it as the breaking of the potters' vessel that is broken in pieces; he shall not spare: so that there shall not be found in the bursting of it a sherd to take fire from the hearth, or to take water withal out of the pit.
The metaphor of a vessel being broken is never about individuals being killed. God didn't kill every Jew. But their rebellion and sin against him caused the demise of their chosen status, even the covenant between them and God. Fast forward to the Millennium and again those who rebel against Christ shall have their wicked organizations broken up, leaving them powerless and unable to organize against Christ during this period of TIME of the reign/rule with a rod of iron. They live to be reigned over. When God allows satan to deceive them, then a brief and failed rebellion occurs and they are killed and judged and are no more forever.
Barnes:
As the breaking of the potter’s vessel - That is, as an earthen, fragile vessel, which is easily dashed to pieces. The image here is all drawn from the bursting forth, or the complete ruin of the swelling wall; but the sense is, that the Jewish republic would be entirely broken, scattered, demolished.
