Exactly right. Here, I think, is that very point:
Zec 12:6 In that day will I make the governors of Judah like an hearth of fire among the wood, and like a torch of fire in a sheaf; and they shall devour all the people round about, on the right hand and on the left: and Jerusalem shall be inhabited again in her own place, even in Jerusalem.
Zec 12:7 The LORD also shall save the tents of Judah first, that the glory of the house of David and the glory of the inhabitants of Jerusalem do not magnify themselves against Judah.
Zec 12:8 In that day shall the LORD defend the inhabitants of Jerusalem; and he that is feeble among them at that day shall be as David; and the house of David shall be as God, as the angel of the LORD before them.
Zec 12:9 And it shall come to pass in that day, that I will seek to destroy all the nations that come against Jerusalem.
Zec 12:10 And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.
Notice, This is all about Judah. The Jews. Whom we call Israel today. Not anyone else. Allegorize THAT.
Zec 12:9 And it shall come to pass in that day, that I will seek to destroy all the nations that come against Jerusalem.
all the nations that do come against spiritual Jerusalem ( the Church ) will be destroyed on the last day, when Jesus comes again in judgement. this IN NO WAY is talking about the physical city in the middle east called Jerusalem, which is a type of the heavenly Jerusalem.
