John Gill, on Esth 8:7

“And king Assuerus answered Esther the queen, and Mardochai the Jew: I have given Aman’s house to Esther, and I have commanded him to be hanged on a gibbet, because he durst lay hands on the Jews.”

“Write ye also for the Jews as it liketh you,.... Whatever may be thought fit and proper for their safety and security: in the king's name, and seal it with the king's ring; as the former letters were: for the writing which is written in the king's name, and sealed with the king's ring, may no man reverse; which is a reason both for the writing and sealing of the present letters in this manner, and why the former could not be reversed; nor does it appear that they were, but that, in virtue of them, the people had power to rise and kill the Jews on the day appointed, if they dared, or were so disposed; and these empowered the Jews to rise in their own defence, and kill all that made any attempts upon them, for which they had the royal authority; and these letters coming after the other, though they did not formally reverse them, which might not be done, yet rendered them ineffectual.”
