That sounds like a good candidate. Except at that time hadn't he conquered everyone and was the only King at the time?
"...as dust to his sword...", nevertheless there was still Assyria, the Persians, and Medes, as well as Macedonia, and the Greeks.
The 'Rule' in this context apparently includes conquest over kings.
Nebuchadnezzar of Chaldea is from the East, and he was referred to as a King of kings subsequently inheriting the specified jurisdiction once bestowed upon Adam.
Who also was planted Eastward in the garden, and given jurisdiction over every sovereign being.
When Adam fell by iniquity, he fell from Righteousness.
"...the Resurrection of the Dead. It is sown in corruption; it is Raised in incorruption:
It is Sown in Dishonour; it is Raised in Glory: it is Sown in Weakness; it is Raised in Power:
It is Sown a Natural body; it is raised a Spiritual body. There is a Natural body, and there is a Spiritual body.
And so it is written, The First man Adam was made a Living soul; the last Adam was made a Quickening spirit.
Howbeit that was not First which is Spiritual, but that which is Natural; and Afterward that which is Spiritual.
The First Man is of the earth, earthy: the Second Man is the Lord from heaven.
As is the earthy, such are they also that are Earthy: and as is the Heavenly, such are they also that are Heavenly.
Therefore, as we have borne the image of the Earthy, we shall also bear the image of the Heavenly. [1st Corinthians 15:42-49]
This passage refers to Adam as a Resurrected Being, Raised in כבוד Glory, Bearing the image of the Lord, and being a Quickening Spirit.
Yet the Son of Adam said, "...as the Father raises up the dead, and Quickens them; even so the Son Quickens whom he will." [John 5:21]
Thus Adam, and the Son of Adam are both Quickening Spirits.
The reference to the First Man being Earthly, and the Second Man being the Lord from Heaven' pertains to John who is referred to as Risen, and as the Greatest Man born of a woman, yet this is what he said concerning the Son;
"He must increase, but I must decrease.
He that comes from above is above all: he that is of the Earth is Earthly, and speaks of the Earth: he that comes from Heaven is above all." [John 3:30-31]
John came in the Way of Righteousness, proclaiming to be the Comforter mentioned in Isaiah, Crying in the Wilderness, saying, Make Straight the Path of Îyéhûʷəʰ.
However, in Isaiah 51 those who follow after Righteousness are told to Seek our Father Abvraham, for he Alone was Called, and כי (kéyî) Thereby shall Îyéhûʷəʰ Comfort Zion.
Thus John was proclaiming to be Abvraham (as safely as he could, I imagine), i.e., The Father of Many Nations, by whom every family of the earth will be Blessed, said Elohym, however without any contradiction the Less is Blessed by the Greater, subsequently making Abvraham the Greatest Man born of a woman.
Abvraham was declared Righteous because he Believed Elohym, and John "...came for a Witness, to Bear Witness of the Light, that Every One through him might Believe. " [John 1:6-7]
No one has seen the Father, only because they do not Believe the one who is Sent, and as the Father was preaching through the Son, the Son was in the Bosom of the Father testifying.
John means Grace, and the Son was full of Grace.
That is why John informed many of the Scribes, and Pharisee, 'Do not think to yourself saying,
We have Abvraham for a Father, for I'm telling you, Elohym is able מאזרח (məzərəkʰ) 'to Raise' children unto Abvraham from these Stones (meaning, his testicles)." [Mathew 3:9]
And as Îyéshûʷəʰ declared, 'Your father Abvraham rejoiced to see my day: and was glad when he saw it." [John 8:56]
For as soon as the voice of Mary's salutation sounded in the ears of John's mother, John Leaped in her womb for Joy." [Luke 1:44]
"Yet you have not known him; but I know him: and if I were to say, I know him not, I would be a liar like you: but I know him, and keep his saying." [John 8:55]
Because they are not דע 'able to Ascertain and Declare' whether the Baptism of John comes from Heaven or Men, when the Master of the House is Risen, and has to shut the Door, then they will stand outside knocking, saying Lord, Lord open up for us;
Yet he will say, I am not דע 'able to Ascertain and Declare' where you are from, go away...
