(23) Hanged on a tree.--Were crucified; a common punishment among the Persians, especially on rebels (Herod. iii. 120, 125, 159, &c). The dead body of Leonidas was crucified by Xerxes' orders after the desperate stand at Thermopylae.

Book of the chronicles.--A sleepless night of Xerxes accidentally brought this matter, after it had been forgotten, before the king's mind. Herodotus often refers to these Persian Chronicles (vii. 100; viii. 85, 90).

Verse 23. - It was found out. The subsequent history shows that Mordecai's information was found to be correct, since he was ultimately adjudged to have deserved the highest possible reward (Esther 6:6-10). The two conspirators were condemned to death and hanged on a tree, i.e. crucified or impaled, as traitors and rebels commonly were in Persia (see Herod., 3 159; 4:43; 'Behist. Inscr.,' col. 2. pars. 13, 14; col. 3. par. 8). And it was written in the book of the chronicles. Historiographers were attached to the Persian court, and attended the monarch wherever he went. We find them noting down facts for Xerxes at Doriscus (Herod., 7:100), and again at Salamis (ibid. 8:90). They kept a record something like the acta diurna of the early Roman empire (Tacit., 'Ann.,' 13:31), and specially noted whatever concerned the king. Ctesias pretended to have drawn his Persian history from these "chronicles" (up. Diod. Sic., 2:32), and Herodotus seems to have obtained access to some of them (see the writer's 'Herodotus,' Introduction, ch. 1.h p. 56). Before the king. i.e. "in the king's presence." This was not always the case; but when the matter was very important the king exercised a supervision over what was written.

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.And when inquisition was made of the matter, it was found out,.... That these two men had entered into a conspiracy to take away the king's life; full proof and evidence were given of it:

therefore they were both hanged on a tree; Josephus (e) says they were crucified; but hanging was frequent among the Persians, as Grotius observes, and better agrees with the word here used:

and it was written in the book of the chronicles before the king; in a diary kept by the king's order, in which memorable events were set down, and might be done in the presence of the king, as well as the book lay open before him to read at any time; and this is observed to agree with the manner of Xerxes, who is reported (f) to sit on a throne of gold to behold a sea fight between the Grecians and Persians, and had several scribes by him to take down whatever was done in the fight.
