This good service which Mordecai did to the government, in discovering a plot against the life of the king, is here recorded, because the mention of it will again occur to his advantage. No step is yet taken towards Haman's design of the Jews' destruction, but several steps are taken towards God's design of their deliverance, and this for one. God now gives Mordecai an opportunity of doing the king a good turn, that he might have the fairer opportunity afterwards of doing the Jews a good turn. 1. A design was laid against the king by two of his own servants, who sought to lay hands on him, not only to make him a prisoner, but to take away his life, Est 2:21. Probably they resented some affront which they thought he had given them, or some injury which he had done them. Who would be great, to be so much the object of envy? Who would be arbitrary, to be so much the object of ill-will? Princes, above any mortals, have their souls continually in their hands, and often go down slain to the pit, especially those who caused terror in the land of the living. 2. Mordecai got notice of their treason, and, by Esther's means, discovered it to the king, hereby confirming her in and recommending himself to the king's favour. How he came to the knowledge of it does not appear. Whether he overheard their discourse, or whether they offered to draw him in with them, so it was that the thing was known to him. This ought to be a warning against all traitorous and seditious practices: though men presume upon secresy, a bird of the air shall carry the voice. Mordecai, as soon as he knew it, caused it to be made known to the king, which ought to be an instruction and example to all that would be found good subjects not to conceal any bad design they know of against the prince or the public peace, for it is making a confederacy with public enemies. 3. The traitors were hanged, as they deserved, but not till their treason was, upon search, fully proved against them (Est 2:23), and the whole matter was recorded in the king's journals, with a particular remark that Mordecai was the man who discovered the treason. He was not rewarded presently, but a book of remembrance was written. Thus with respect to those who serve Christ, though their recompence is adjourned 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, Heb 6:10.
