All this came upon King Nebuchadnezzar…he was walking about the royal palace of Babylon. The king spoke, saying, "Is not this great Babylon, that I have built for a royal dwelling by my mighty power and for the honor of my majesty?" While the word was still in the king's mouth, a voice fell from heaven: "King Nebuchadnezzar, to you it is spoken: the kingdom has departed from you." (Daniel 4:28-31)
I find Nebuchadnezzar to be an interesting character. Proud, arrogant, but made a complete turnaround towards the end by God's grace. Nebuchadnezzar is the complete antithesis of the AC because we know the AC just grows more prideful and never considers repenting. I'd like to meet Nebuchadnezzar in heaven.
By the way, Nebuchadnezzar's reign started off the Times of the Gentiles, so in effect, he is the first king of the gentiles and the AC being the last king. Interesting.
