Esther 2:20-23
2:20 Esther was still not divulging her lineage or her people,
just as Mordecai had instructed her.
Esther continued to do whatever Mordecai said, just as she had done when he was raising her.
2:21 In those days while Mordecai was sitting at the king’s gate, Bigthan and Teresh, two of the king’s eunuchs who protected the entrance, became angry and plotted to assassinate King Ahasuerus.
2:22 When Mordecai learned of the conspiracy, he informed Queen Esther, and Esther told the king in Mordecai’s behalf.
2:23 The king then had the matter investigated and, finding it to be so, had the two conspirators hanged on a gallows. It was then recorded in the daily chronicles in the king’s presence.
