John Gill Commentary Esther 9

Now in the twelfth month, that is the month Adar, on the
thirteenth day of the same
Of which see (Esther 3:13) ,

when the king's commandment and his decree drew near to be put in
execution ;
even both his commandments and decrees, the one empowering the enemies of the Jews on that day to destroy them, and the other empowering the Jews to act both defensively and offensively against their enemies:

in the day that the enemies of the Jews hoped to have power over them ;
by virtue of the first decree of the king; and notwithstanding the second, they might hope to have it because of their superior numbers:

though it was turned to the contrary, that the Jews had rule over them
that hated them ;
it proved the reverse, partly through the second decree in favour of the Jews, and partly through the fear of them that fell upon their enemies; because the court was on their side, and the officers everywhere, and especially their God filled them with courage, and their enemies with terror.

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.

And all the rulers of the provinces, and the lieutenants, and
the deputies, and officers of the king, blessed the Jews
Countenanced them and encouraged them, and gave them all assistance in their power; extolled them, as the word signifies, lifted them up, and spoke well of them, or praised them, as the Targum:

because the fear of Mordecai was upon them ;
he being now chief minister, they might fear, if they took part with the enemies of the Jews against them, they might be turned out of their places.

For Mordecai was great in the king's house
Not only over Esther's affairs, but was one of the king's counsellors, and was the chief minister of state:

and his fame went out throughout all the provinces ;
what a favourite he was of the king, as well as a relation of the queen, and how wise and just his administrations were:

for this man Mordecai waxed greater and greater ,
was more and more in the king's favour, and had offices of honour and trust heaped upon him, and increased both in wealth and power.

Thus the Jews smote all their enemies with the stroke of the
sword, and slaughter, and destruction
Some with swords, and others with clubs, and staves; as the Targum; and such like slaughtering weapons of destruction:

and did what they would unto those that hated them ;
being then entirely at their will, and under their power.
