פּירוש אויף אסתר 1:4

“One hundred and eighty days” [1:4]. He made banquets and displayed his great wealth for one hundred and eighty days. Here one asks a question. Why did he not simply say six months? He might have shown his treasures, but one hundred and eighty days is six months, as he later says concerning the clothing of the women was six months.⁶Esther, 2:12. The reason is, that this teaches us that for one hundred and eighty days he showed different treasures and novelties every day.

[For] many days. He made a feast for them.¹²I.e., “for many days” refers back to “the feast” [v. 3] and not to the exhibition of “the affluence and eminence of his kingdom.” [v. 4] (Sifsei Chachomim)

QUESTIONS:
WHY did Achashverosh feel the need to display his wealth to the assembled nations?WHAT is the point of the repetitive “honor of his great splendor”?WHY are we told that this display lasted for “many days”?
