Esther 2:18-22

Then the king held a great banquet, Esther’s banquet, for all his officials and his servants; he also made a holiday for the provinces and gave gifts in proportion to the king’s bounty.

Now when the virgins were gathered together for the second time, then Mordecai was sitting at the king’s gate.

Esther still had not revealed her relatives or her people, just as Mordecai had instructed her; for Esther did what Mordecai told her just as she had when under his care. Mordecai Saves the King

In those days, while Mordecai was sitting at the king’s gate, Bigthan and Teresh, two of the king’s officials from those who guarded the door, became angry and sought to attack King Ahasuerus.

But the plot became known to Mordecai and he informed Queen Esther, and Esther told the king in Mordecai’s name.
