Esther 2:16-17

So Esther was taken to King Ahasuerus, to his royal palace in the tenth month, that is, the month of Tebeth (Dec-Jan), in the seventh year of his reign. Now the king loved Esther more than all the other women, and she found favor and kindness with him more than all the [other] virgins, so that he set the royal crown on her head and made her queen in the place of Vashti.
