Esther 8:9 So the king’s scribes were called at that time in the third month (that is, the month Sivan), on the twenty-third day; and it was written according to all that Mordecai commanded to the Jews, the satraps, the governors, and the princes of the provinces which extended from India to Ethiopia, 127 provinces, to every province according to its script, and to every people according to their tongue as well as to the Jews according to their script and their tongue.
Esther 8:10 And he wrote in the name of King Ahasuerus and sealed it with the king’s signet ring and sent letters by the hand of couriers on horses, riding on steeds sired by the royal stud.
Esther 8:11 In them the king gave the Jews who were in each and every city the right to assemble and to make a stand for their lives, to destroy, to kill, and to cause to perish the entire military force of any people or province which would act as their adversaries, including little ones and women, and to plunder their spoil,
Esther 8:12 on one day in all the provinces of King Ahasuerus, the thirteenth day of the twelfth month (that is, the month Adar).

The verse centers on "king", "gave", "jews", "each", "city", "right", "assemble", and "make". It is saying that the verse draws attention to "king" and "gave", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "And he wrote in the name of..." into verse 12's "on one day in all the provinces...", so "king" and "gave" belong inside that flow. In Esther context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "king" and "gave" with trust shaped by these words, not by a vague optimism outside the passage.
