John Gill Commentary Zechariah 12:6

"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." — Zechariah 12:6 (ASV)

In that day will I make the governors of Judah like a
hearth of fire among the wood
As a large hearth of fire, with wood all about it, devours and consumes it; so shall the governors of Judah be to the nations that shall come up against Jerusalem. The Targum renders it, ``as a garment of fire among wood:'' and like a torch of fire in a sheaf ;
of wheat, which presently destroys it; see (Obadiah 1:18) :

and they shall devour all the people round about, on the right hand
and on the left ;
on the south and on the north, as the Targum interprets it. The phrase denotes the utter destruction of the people on all sides:

and Jerusalem shall be inhabited again in her own place, [even] in
Jerusalem ;
upon that very spot of ground which was formerly called Jerusalem shall the city be built again, and inhabited; and shall continue, notwithstanding the attempts of all the nations of the earth to destroy it; see (Jeremiah 30:18) .
