Midrasch zu Divrej Hajamim II 32:12

“It was during the days of Aḥashverosh; that [hu] Aḥashverosh who reigned from India to Kush, one hundred and twenty-seven provinces” (Esther 1:1). Hu [appears] five [times] for evil, and five for good. Five for evil: “He [hu] was a mighty hunter”⁴Nimrod. (Genesis 10:9); “he is [hu] Esau, father of Edom” (Genesis 36:43); “this is [hu] Datan and Aviram” (Numbers 26:9); “he is [hu] King Aḥaz” (II Chronicles 28:22); “that [hu] Aḥashverosh” (Esther 1:1). Five for good: “Abram, he is [hu] Abraham” (I Chronicles 1:27); “that [hu] Aaron and Moses…that [hu] Moses and Aaron” (Exodus 6:26–27); “David was [hu] the youngest” (I Samuel 17:14); “he [hu], Yeḥizhiyahu” (II Chronicles 32:30); “he [hu], Ezra, came up from Babylon” (Ezra 7:6). Rabbi Berekhya said in the name of the Rabbis from there: We have one that is better than all of them: “He is [hu] the Lord our God; His judgments are throughout the land” (Psalms 105:7), whose attribute of mercy is forever.
