Conspiracies inside the palace were ordinary occurrences in Persia. Xerxes was ultimately murdered by Artabanus, the captain of the guard, and Aspamitras, a chamberlain and eunuch.

Mordecai sat in the kings gate - Mordecai might have been one of the officers of the king, as the gate was the place where such usually attended to await the king's call. It is not likely that he was the porter; had he been only such, Haman could have removed him at once.

Two of the king's chamberlains - Eunuchs. Why they conspired against the life of the king, we are not informed. The Targum says that they found out that Esther had intended to use her influence with the king to get them removed from their office, and Mordecai put in their place; therefore they determined to poison Esther, and slay the king in his bedchamber. It is very likely that they were creatures of Haman, who probably affected the kingdom, and perhaps were employed by him to remove the king, and so make his way open to the throne.

In those days, while Mordecai sat in the king's gate,.... Being, as before observed, an officer at court:

two of the king's chamberlains, Bigthan and Teresh, of those that kept the door; of the inner court, as Aben Ezra, of the doors of his bedchamber; perhaps they were the chief of his bodyguards, as the Septuagint version; in later times, such officers were about the chambers of great personages as their guards (a):

these were wroth, and sought to lay hand on the King Ahasuerus; to poison him, as Jarchi and both the Targums; however, to take away his life by some means or another. Gorionides (b) says their design was, while the king was asleep, to cut off his head, and carry it to the king of Greece; there being at that time great wars between the kingdom of Greece and the kingdom of Persia, which exactly agrees with the times of Xerxes, and with this part of his reign, about the seventh year of it, what was the occasion of this wrath is not said, it is thought to be either the divorce of Vashti, whose creatures they were, or the marriage of Esther, and particularly the promotion of Mordecai, fearing they should be turned out of their places; so the former Targum.

The definition of time in Esther 2:19 is again take up by the words: in those days; then the explanatory clause, Esther 2:20, is repeated; and after this we are informed what it was that had then occurred. In those days Bigthan and Teresh, two of the king's courtiers, who were the threshold-keepers (palace-watchers, lxx ἀρχισωματοφύλακες), were wroth, and sought to lay hands on King Ahashverosh, i.e., to slay him. Esther 2:22. This thing was known to Mordochai, and by him communicated to Esther, who told it, in Mordochai's name, to the king. Esther 2:23. The matter was investigated (sc. by the king), and found out, sc. as Mordochai had testified. The two criminals were hanged on a tree, i.e., impaled on a stake, a sort of crucifixion, - see rem. on Esther 6:11, - and the circumstance entered in the book of the chronicles, i.e., the chronicles of the kingdom. המּלך לפני, before the king, i.e., in his presence, immediately after sentence had been passed by a court over which the monarch presided.

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 {n} hand on the king Ahasuerus.

(n) Meaning, to kill him.

Es 2:21-23. Mordecai, Discovering a Treason, Is Recorded in the Chronicles.

21. In those days . two of the king's chamberlains . were wroth and sought to lay hand on the king, &c.-This secret conspiracy against the king's life probably arose out of revenge for the divorce of Vashti, in whose interest, and at whose instigation, these eunuchs may have acted. Through the vigilance of Mordecai, whose fidelity, however, passed unnoticed, the design was frustrated, while the conspirators were condemned to be executed and as the matter was recorded in the court annals, it became the occasion afterwards of Mordecai's preferment to the place of power and influence for which, in furtherance of the national interests of the Jews, divine providence intended him.

2:21-23 Good subjects must not conceal any bad design they know of against the prince, or the public peace. Mordecai was not rewarded at the time, but a remembrance was written. Thus, with respect to those who serve Christ, though their recompence is not till the resurrection of the just, yet an account is kept of their work of faith and labour of love, which God is not unrighteous to forget. The servant of God must be faithful to every trust, and watchful for those who employ him. If he appear to be neglected now, he will be remembered hereafter. None of our actions can be forgotten; even our most secret thoughts are written in lasting registers, Re 20:12.
