BSB Esther 2:10 Esther did not reveal her people or her lineage, because Mordecai had instructed her not to do so. 11 And every day Mordecai would walk back and forth in front of the court of the harem to learn about Esther’s welfare and what was happening to her.
Obviously, Esther and Mordecai knew each other.
21In those days, while Mordecai was sitting at the king’s gate, Bigthane and Teresh, two of the king’s eunuchs who guarded the entrance, grew angry and conspired to assassinate King Xerxes.
22When Mordecai learned of the plot, he reported it to Queen Esther, and she informed the king on Mordecai’s behalf.
Obviously, Mordecai could access the king through Esther.
Esther 3:5 When Haman saw that Mordecai would not bow down or pay him homage, he was filled with rage. 6And when he learned the identity of Mordecai’s people, he scorned the notion of laying hands on Mordecai alone. Instead, he sought to destroy all of Mordecai’s people, the Jews, throughout the kingdom of Xerxes.
Did Haman underestimate the reach of Modecai and the Jews when he proposed the genocide?
