IRON-Inverse Relationship?

You will rule them with an iron scepter*; you will dash them to pieces like pottery."
Psalm 2:9 NIV

Footnote:
* Or will break them with a rod of iron

And whereas thou sawest iron mixed with miry clay, they shall mingle themselves with the seed of men: but they shall not cleave one to another, even as iron is not mixed with clay. 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.

Daniel 2:43,44

And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.

Revelation 19:15

So this IRON He crushes, He uses a scepter (rod) of IRON to do it......Interesting.....

Just some symbolism to contemplate
