21 In those days, while Mordecai was sitting in the king's gate, two of the king's chamberlains, Bigthan and Teresh, of those that kept the threshold, were wroth, and sought to lay hands on the king Ahasuerus. 22 And the thing became known to Mordecai, who showed it unto Esther the queen; and Esther told the king [thereof] in Mordecai's name. 23 And when inquisition was made of the matter, and it was found to be so, they were both hanged on a tree: and it was written in the book of the chronicles before the king.

Commentary on Esther 2:21-23

(Read Esther 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, Revelation 20:12.
