John Gill Commentary Zechariah 14:11

"And men shall dwell therein, and there shall be no more curse; but Jerusalem shall dwell safely." — Zechariah 14:11 (ASV)

And [men] shall dwell in it
In great numbers, in much peace and safety, and from generation to generation: Aben Ezra says, Messiah the son of David will now come:

and there shall be no more utter destruction ;
no wars, nor desolations by them, in a civil sense; there shall be no more killing, as the Targum, (Isaiah 2:4) (Isaiah 60:17Isaiah 60:18) no "cherem", no anathema, in a religious sense; in the old translation it is, "and there shall be no more cursing"; there will be no curse in the Jerusalem state, (Revelation 22:3) which words seem to be taken from hence; no cursed thing, nor cursed person, or any curse or anathema denounced against any; no Popish bulls and anathemas, nor any other:

but Jerusalem shall be safely inhabited ;
the inhabitants of it shall dwell securely, without any apprehension of danger, and having no enemies to fear; though, before this safe and happy state, there will be many enemies; and what will become of them is shown in the following verses.
