In the first chapter of sefer Ezra we read that Koresh sent all the utensils that had been stolen by Nevuchadnetzar back to Yerushalayim as part of the rebuilding of the Beit Hamikdash. However the gemarah megillah 12a based on the pasuk in Esther 1:7 seems to indicate that the utensils that Achashveirosh used at his party were those of the Beit Hamikdash. If that is so, how did Achashveirosh have those keilim in his possession? Were they taken back from Yerushalayim? Is there any commentator who explains this?
Rabbi Hayyim Angel in a lecture on Megillat Esther posits that the gemarah should not be taken literally. Rather, like the gemarah (ibid) which mentions Achashveirosh wearing the clothing of the kohen gadol, this gemarah is alluding to a theme that relates to Achashveirosh being portrayed as eclipsing God and Shushan as the 'new' Jerusalem
None of the Kelim, (including the clothes of the Kohen Godol) that the Medrashim say King Achosvairosh used at his Party, were the Kelim that Koresh (King Cyrus) gave back to Daniel (Shasbazzar).
King Cyrus only gave the Jews back Knives, Bowls to gather the blood and instruments to sprinkle the blood. That was All. (See Below)
It's clearly written in the "1st Pereck of Sefer Ezra" that Koresh (King Cyrus) took out the many "New Gold & Silver knifes, bowls to catch and sprinkle the Blood of Korbonos, made of silver new & old" from King Nebuchadnezzar's Personal Idol House and ordered it be given to the Jews for the (L'havdel) Bais Hamikdash, listing the number of vessels.
