Hebrew: וַשְׁתִּי —transliteration: Vashti
This is the queen of King Ahasuerus of Persia, who was deposed from her royal dignity because she refused to obey the king when he desired her to appear in the banqueting hall of Shushan the palace (Esther 1:10-12).
On the seventh day, when the heart of the king was merry with wine, he commanded Mehuman, Biztha, Harbona, Bigtha and Abagtha, Zethar and Carkas, the seven eunuchs who served in the presence of King Ahasuerus, to bring Queen Vashti before the king with her royal crown, in order to show the peoples and the princes her beauty, for she was lovely to look at. But Queen Vashti refused to come at the king's command delivered by the eunuchs.
At this the king became enraged, and his anger burned within him. —Esther 1:10-12 ESV
