What events and attributed statements does Esther Chapter 13 record?

The imperial decree issued by King Artaxerxes addressed the princes and governors across the one hundred and twenty-seven provinces from India to Ethiopia. Declaring his desire to govern his vast realm with clemency and secure universal tranquility without terror, the sovereign recounted consulting his counselors on how to maintain public concord. His chief minister Aman, honored second only to the king for wisdom and fidelity, reported the existence of a singular people dispersed throughout the world whose perverse customs, novel laws, and contempt for royal commands disrupted the unity of nations. Concluding that this nation stood in active hostility to all mankind, the king decreed that everyone designated by Aman—whom he regarded as a father—must be utterly eradicated, including their wives and children, on the fourteenth day of the twelfth month, Adar, with none to have pity; the letter describes these men going down to hell in one day to restore the empire’s peace.

The account then presents Mardochai, who turned to the Lord, recalling all His wondrous deeds, and poured out his heart in prayer. Acknowledging that the Almighty King holds sovereign authority over heaven, earth, and all creation, Mardochai affirmed that no mortal power can resist God's determination to deliver Israel. Addressing the Lord as knowing all things, he declared that his refusal to bow down and worship the haughty Aman had not sprung from arrogance, vainglory, or personal pride, insisting that for the deliverance of his people he would gladly have kissed even the steps of Aman’s feet. Rather, he had refused reverence solely out of holy fear, lest he transfer the worship due to God alone onto a mortal man.

Appealing to the Lord God of Abraham, Mardochai pleaded for mercy upon His people, urging Him not to abandon the chosen portion He had redeemed from the bondage of Egypt. He prayed that the Lord would hear their cry, turn their sorrow into rejoicing, and preserve their lives so they might continue singing praises to His holy name instead of having their mouths silenced forever. Moved by the same mortal dread, all Israel joined with one mind in earnest supplication, crying aloud to God as they beheld impending destruction hanging over their heads.

This copied letter says the fourteenth of Adar; the earlier letters in chapter 3 say the thirteenth. Both admitted readings are retained without harmonization.
