Isaiah 13:2

The prophet hears a call to war. From whom it issues, and to whom or against whom it is directed, still remains a secret; but this only adds to the intensity."On woodless mountain lift ye up a banner, call to them with loud sounding voice, shake the hand, that they may enter into gates of princes!" The summons is urgent: hence a threefold signal, viz., the banner-staff planted on a mountain "made bald" (nishpeh, from which comes shephi, which only occurs in Isaiah and Jeremiah), the voice raised high, and the shaking of the hand, denoting a violent beckoning - all three being favourite signs with Isaiah. The destination of this army is to enter into a city of princes (nedı̄bı̄m, freemen, nobles, princes, Psa 107:40, cf., Psa 113:8), namely, to enter as conquerors; for it is not the princes who invite them, but Jehovah.

Hitherto the prophecies of this book related only to Judah and Israel, and Jerusalem especially; but now the prophet begins to look abroad, and to read the doom of divers of the neighbouring states and kingdoms: for he that is King of saints is also King of nations, and rules in the affairs of the children of men as well as in those of his own children. But the nations to whom these prophecies do relate were all such as the people of God were in some way or other conversant and concerned with, such as had been kind or unkind to Israel, and accordingly God would deal with them, either in favour or in wrath; for the Lord's portion is his people, and to them he has an eye in all the dispensations of his providence concerning those about them, Deu 32:8, Deu 32:9. The threatenings we find here against Babylon, Moab, Damascus, Egypt, Tyre, etc., were intended for comfort to those in Israel that feared God, but were terrified and oppressed by those potent neighbours, and for alarm to those among them that were wicked. If God would thus severely reckon with those for their sins that knew him not, and made no profession of his name, how severe would he be with those that were called by his name and yet lived in rebellion against him! And perhaps the directing of particular prophecies to the neighbouring nations might invite some of those nations to the reading of the Jews' Bible, and so they might be brought to their religion. This chapter, and that which follows, contain what God had to say to Babylon and Babylon's king, who were at present little known to Israel, but would in process of time become a greater enemy to them than any other had been, for which God would at last reckon with them. In this chapter we have, I. A general rendezvous of the forces that were to be employe…

13:2 A signal flag or banner that could be seen clearly from a great distance was often placed on a bare hilltop as a call to battle. • God stands against Babylon as the symbolic representative of all evil kingdoms.
