Esther 2:21; Esther 2:22

21 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 lay hands on King Ahasuerus.

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