John Gill Commentary Esther 9:2

"the Jews gathered themselves together in their cities throughout all the provinces of the king Ahasuerus, to lay hand on such as sought their hurt: and no man could withstand them; for the fear of them was fallen upon all the peoples." — Esther 9:2 (ASV)

The Jews gathered themselves together in their cities, throughout all the provinces of King Ahasuerus Wherever they lived:

to lay hand on such as sought their hurt; who not only threatened them what they would do on this day, but were risen up in arms in quest of them:

and no man could withstand them, for the fear of them fell upon all people; when they understood that Haman was hanged, and Mordecai the Jew advanced, and that the queen herself was a Jew, and that the Jews had the royal grant to act both defensively and offensively; and no doubt but the panic was of God.
