Scripture tells us that when Jesus came to earth, He was not here to be the type of Messiah that the people were expecting. Today when believers read the old testament we can see that it conveyed the true message about the Christ as well as the new testament.
I'm not very knowledgeable about anything to do with Kabbalah and it's esoteric reference made about Zion. I hear people speak of Zion in such a negative way these days. Perhaps that is what they are talking about. How else is scripture going to point out to us about the New Jerusalem (heavenly city of God), without starting out giving us a simple image of it in the old testament?
John 3:12 states I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things?
Jesus is the King of Kings. The only perfect and righteous King.
