After these things, when the wrath of King Ahasuerus subsided, he remembered Vashti, what she had done, and what had been decreed against her.
Then the king's servants who attended him said: "Let beautiful young virgins be sought for the king;
and let the king appoint officers in all the provinces of his kingdom, that they may gather all the beautiful young virgins to Shushan the citadel, into the women's quarters, under the custody of Hegai the king's eunuch, custodian of the women. And let beauty preparations be given them.

Then let the young woman who pleases the king be queen instead of Vashti." This thing pleased the king, and he did so.
In Shushan the citadel there was a certain Jew whose name was Mordecai the son of Jair, the son of Shimei, the son of Kish, a Benjamite.
Kish had been carried away from Jerusalem with the captives who had been captured with Jeconiah king of Judah, whom Nebuchadnezzar the king of Babylon had carried away.
