What do you know about Jerusalem?

Do you know that Jerusalem was settled in the 4th millennium BCE and it is a city of lion (A lion is the emblem of Jerusalem).
I lived in this city in 2010 and 2012. It was interesting experience for me. But I don’t understand this city. Yes, it will be very presumptuously to believe, that I can understand Jerusalem.
My relationship with this city have always been built on trust and respect. As a younger brother trusts older brother, I trusted Jerusalem. But even in this relationship one of us- city with long history, and one of us- 26 years old guy from the Ukraine.
