Zechariah 12

In that day I will make the governors of Judah like a firepan in the woodpile, and like a fiery torch in the sheaves; they shall devour all the surrounding peoples on the right hand and on the left, but Jerusalem shall be inhabited again in her own place—Jerusalem. v.6

Read chapter 12
This chapter speaks of a still future time, the time of tribulation and the Day of the Lord.  We can tell this due to the fact that it's not speaking of Jerusalem's destruction before captivity for Zechariah was a prophet after captivity when they were back in their land. There is the fulfillment of verse ten speaking of Christ's crucifixion "whom they had pierced" but that verse is speaking of looking back at that time in mournful regret, so again future from Christ's earthly ministry.   In verse six here we read of the leaders killing the rebels and fighting back for Jerusalem being used by the Lord in this.  We see this in Joel 3:9-11 as Jerusalem being the Lord's threshing sledge after a time of no wars or the righteous fighting the wicked, 
Proclaim this among the nations:
“Prepare for war!
Wake up the mighty men,
Let all the men of war draw near,
Let them come up.
10 Beat your plowshares into swords
And your pruning hooks into spears;
Let the weak say, ‘I am strong.’”
11 Assemble and come, all you nations,
And gather together all around.
Cause Your mighty ones to go down there, O Lord.

This seems like a final destruction and clean up of the wicked that those in Judah will do by the hand of the Lord.  Even today the city of Jerusalem is a core issue in Israeli and Palestinian wars, it is not the inhabited place that God says it will be yet, but its future has hope and promises.  What are your views and understanding of Jerusalem today in regards to God's holy city?
