Joshua 12

the king of Jerusalem, one; the king of Hebron, one; v.10

Read chapter 12
Whenever you think of Jerusalem in the Bible, one typically thinks of where Jesus lived or the capitol of Israel where David, Solomon and other kings ruled.  Yet the city of Jerusalem had another history before Israel lived there.  Here we see it was in the land of Canaan with a king over this city.  (This king is actually one of the five kings who was taken and hanged back in chapter ten.)  Even before Canaanite world of this land it has been discoverd that Egyptian had rule over Jerusalem and possibly it's first settlement.  We don't see till many years later after Joshua had conqured it when King David makes it officially the capitol where God's temple resides.  In "its long history, Jerusalem has been destroyed 2 times, besieged 23 times, attacked 52 times, and captured and recaptured 44 times. The oldest part of the city was settled in the 4th millennium BCE, making Jerusalem one of the oldest cities in the world" (Wikipedia).
We also look forward to the New Jerusalem noted Revelation 21.  So as you think about Jerusalem may you be in wonder of it's full history and desire for the New Jerusalem.  What city do you desire to go to and why?  What would be the draw for you to visit Jerusalem in the past, today and in the future?
