At that time when Mordecai was sitting in the king's gate, Bigthan and Teresh, two of the king's eunuchs among those who guarded the threshold, became angry and conspired to assassinate King Ahasuerus.

After the matter had been fully investigated, Bigthan and Teresh were hanged on a pole, and this was recorded in the Book of the Chronicles in the presence of the king.

It was found recorded there that Mordecai had reported about Bigthana and Teresh, two of the king's eunuchs who guarded the entrance to the restricted areas of the palace, and that they had conspired to assassinate King Ahasuerus.
