Esther 2:21-22

21In those days, while Mordecai sat within the king’s gate, two of the king’s eunuchs, Bigthan and Teresh, doorkeepers, became furious and sought to lay hands on King Ahasuerus.

22So the matter became known to Mordecai, who told Queen Esther, and Esther informed the king in Mordecai’s name.
