However, Mordecai had no need to make use of his great knowledge of languages; he obtained his information about the plot of the two chamberlains through prophetical channels. Accordingly, he appeared one night in the palace. By a miracle the guards at the gates had not seen him, and he could enter unrestrained. Thus he overheard the conversation between the two conspirators.

Mordecai had more than a single reason for preventing the death of Ahasuerus. In the first place, he desired to secure the king's friendship for the Jews, and more especially his permission for the rebuilding of the Temple. Then he feared, if the king were murdered immediately after his rise to a high place in the state, the heathen would assign as the cause of the disaster his connection with the Jews, his marriage with Esther and the appointment of Mordecai to office.
