Being set up, let him be hanged thereon - Rather, "let him be lifted up and crucified upon it." Crucifixion was the most common form of capital punishment among the Persians.

Let timber be pulled down - Whether this refers to the punishment of hanging and gibbeting of whipping at a post, or of empaling, is not quite clear. In China they tie culprits to posts; and the executioner cuts them open while alive, takes out their bowels, etc. Empaling, thrusting a sharp stake through the body till it comes out at the side of the neck, or hanging, seems to be intended here.

Let his house be made a dunghill - Let it be reduced to ruins, and never more used, except for the most sordid and unclean purposes.

Also I have made a decree, that whosoever shall alter this word,.... Act contrary to this command, will not obey it, but as much as in him lies changes and revokes it:

let timber be pulled down from his house, and being set up, let him, be hanged thereon; that is, let a beam be taken from it, and a gallows or gibbet made of it, and hang him on it:

and let his house be made a dunghill for this; be pulled down, and never rebuilt more; see Gill on Daniel 2:2; see Gill on Daniel 2:9.

To inculcate obedience to his command, Darius threatens to punish its transgression with death: "If any one alters this command, let a beam be torn from his house, and let him be fastened hanging thereon." To alter a command means to transgress or abolish it. אע, a piece of wood, a beam. זקיף, raised on high, is in Syriac the usual word for crucified, and is to be so understood here. מחא, to strike, with על, strike upon, fasten to, nail to. This kind of capital punishment was customary among the Assyrians (Diod. Sic. ii. 1), the ancient Persians, and many other nations, but seems to have been executed in different manners among different people. Among the Assyrians it generally consisted in the impalement of the delinquent upon a sharp strong wooden post; comp. Layard, Nineveh and Babylon, p. 355, and Nineveh and its Remains, p. 379, with the illustration fig. 58. According to Herod. iii. 159, Darius impaled as many as 3000 Babylonians after the capture of their city (ἀνεσκολόπισε). Crucifixion proper, however, i.e., nailing to a cross, also occurred among the Persians; it was, however, practised by nailing the body of the criminal to a cross after decapitation; see the passages from Herodotus in Brissonii de regio Persarum princip. l. ii. c. 215. "And let his house be made a dunghill." See remarks on Daniel 2:5 and 2 Kings 10:27.

Also I have made a decree, that whosoever shall alter this word, let timber be pulled down from his house, and being set up, let him be hanged thereon; and let his house be made a dunghill for this.

let him...: Chaldee, let him be destroyed

11, 12. whosoever shall alter this word-The warning was specially directed against the turbulent and fanatical Samaritans. The extremely favorable purport of this edict was no doubt owing in some measure to the influence of Cyrus, of whom Darius entertained a high admiration, and whose two daughters he had married. But it proceeded still more from the deep impressions made even on the idolatrous people of that country and that age, as to the being and providence of the God of Israel.

6:1-12 When God's time is come for fulfilling his gracious purposes concerning his church, he will raise up instruments to do it, from whom such good service was not expected. While our thoughts are directed to this event, we are led by Zechariah to fix our regard on a nobler, a spiritual building. The Lord Jesus Christ continues to lay one stone upon another: let us assist the great design. Difficulties delay the progress of this sacred edifice. Yet let not opposition discourage us, for in due season it will be completed to his abundant praise. He shall bring forth the head-stone thereof with shoutings, crying, Grace, grace unto it.
