Zechariah 12:6

I will make the princes of Judah They will return and wage war with those who brought them there.

in its place lit. under it.

"And the Lord promises them that on that day the inhabitants of Jerusalem will not need to pray, because He is their God by Himself, and by His will He will make the leaders of Judah like a fiery cauldron in the midst of wood" — meaning like a great bonfire when it is placed on the wood, because "cauldron" comes from the word "kirim" (furnaces). Likewise, they will be like a flaming torch when it burns on the stack. The leaders of Judah will strike right and left at all the nations coming against them and those surrounding them, in such a way that Jerusalem will sit again in its place, and the nations will not conquer or destroy it, as they had intended to do. "And Jerusalem will sit again in its place" — this phrase, repeated again, emphasizes the true meaning which I will explain here, and I have already pointed it out to you. When Jerusalem was destroyed by Titus and the Roman soldiers, its walls were thrown to the ground, and all its houses were ruined, leaving it desolate like a field that is not worked. Later, the emperor Hadrian commanded the city of Jerusalem to be rebuilt. However, it was not rebuilt in the same exact location as it was originally, and the proof of this is that when Jesus was crucified and buried, it is known that his burial place was outside the city of Jerusalem, like other cemeteries which were all outside the city because of impurity. The law states that those condemned to death by the court are taken outside the city (as it says in Leviticus 24:14, "Take the blasphemer outside the camp"). The Rambam writes in his Laws of Sanhedrin that they used to take them six miles away from the city. Since Jesus was crucified and buried there, it shows that the city was not built in its original place, but rather in the area of the previous burial grounds. Therefore, when it says here, "Jerusalem will sit again in its place," the prophet needed to say "again in Jerusalem" to indicate that the city will not remain in its current location, but rather will return to its original place.
