What does Zechariah 12:6 mean?

In that day will I make the chieftains of Judah like a pan of fire among wood, and like a flaming torch among sheaves; and they shall devour all the peoples round about, on the right hand and on the left; and they of Jerusalem shall yet again dwell in their own place, even in Jerusalem.

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.

In that day will I make the chieftains of Judah like a pan of fire among wood, and like a flaming torch among sheaves; and they shall devour all the peoples round about, on the right hand and on the left; and they of Jerusalem shall yet again dwell in their own place, even in Jerusalem.

In that day I will make the families of Judah like a pot with fire in it among trees, and like a flaming stick among cut grain; they will send destruction on all the peoples round about, on the right hand and on the left: and Jerusalem will be living again in the place which is hers, that is, in Jerusalem.

In that day I make the leaders of Judah As a hearth of fire among trees, And as a torch of fire in a sheaf, And they have consumed--on the right and on the left--all the peoples round about, And Jerusalem hath inhabited again her place in Jerusalem.

In that day I will make the governors of Juda like a furnace of fire amongst wood, and as a firebrand amongst hay: and they shall devour all the people round about, to the right hand, and to the left: and Jerusalem shall be inhabited again in her own place in Jerusalem.

In that day will I make the leaders of Judah like a hearth of fire among wood, and like a torch of fire in a sheaf; and they shall devour all the peoples round about, on the right hand and on the left; and Jerusalem shall dwell again in her own place, in Jerusalem.
