Esther 2:21

And two chamberlains of the king, the chiefs of the body-guard, were grieved, because Mardochaeus was promoted; and they sought to kill king Artaxerxes.

In those days, while Mordecai sat in the king’s gate, two of the king’s chamberlains, Bigthan and Teresh, of those which kept the door, were wroth, and sought to lay hand on the king Ahasuerus.

In those days, while Mordecai was sitting in the king’s gate, two of the king’s eunuchs, Bigthan and Teresh, who were doorkeepers, were angry, and sought to lay hands on the King Ahasuerus.
