(2) Lift ye up a banner upon the high mountain . . .--Strictly speaking, a bare mountain. where there were no trees to hide the standard round which the forces that the prophet sees were to rally. The word and thought are the same as in Isaiah 5:26; but there the summons lies for the invaders of Israel, here for its avengers. The voice that summons is, as the next verse shows, that of Jehovah. The "shaking the hand" is, as in Isaiah 10:32, the act of the generals pointing with emphatic gesture to the city that is to be destroyed.

The gates of the nobles.--The word is used to heighten the contrast between the greatness of the city to be destroyed, with its gates that had witnessed for centuries the entrance of kings and princes, and the wild roughness of the barbarian destroyers.

Verse 2. - Lift ye up a banner; rather, a standard - "an ensign," as in Isaiah 5:26: 11:12. "Ensigns" were used both by the Assyrians and the Egyptians. "Banners," or flags, do not seem to have been employed in the ancient world. Upon the high mountain; rather, upon a bare mountain - one that was clear of trees, so that the signal might be the better seen from it. God's army having to be summoned against Babylon, the summons is made in three ways:

(1) by a signal or ensign lifted up on a high hill;

(2) by a loud call or shout; and

(3) by waving or beckoning with the hand.

The whole description is, of course, pure metaphor. That they may go into the gates of the nobles. Either that they may enter into the palaces of the grandees in Babylon, or that they may take the towns of the tributary princes.

13:1-5 The threatenings of God's word press heavily upon the wicked, and are a sore burden, too heavy for them to bear. The persons brought together to lay Babylon waste, are called God's sanctified or appointed ones; designed for this service, and made able to do it. They are called God's mighty ones, because they had their might from God, and were now to use it for him. They come from afar. God can make those a scourge and ruin to his enemies, who are farthest off, and therefore least dreaded.Lift ye up a banner upon the high mountain,.... Or "upon the mountain Nishphah"; some high mountain in Media or Persia, proper to set a standard on, or erect a banner for the gathering men together, to enlist themselves as soldiers, and so form an army to march into the land of Chaldea. Vitringa thinks there may be an allusion to the mountain Zagrius, which divides Media and Persia from Assyria, mentioned by Strabo (x). Or "upon a high mountain"; any high mountain fit for such a purpose; or "against the high mountain", as some (y) read it; meaning Babylon, called a mountain, Jeremiah 51:25 not because of its situation, for it was in a plain; but because of its eminence above other cities and states. The Targum is,

"against the city that dwells securely, lift up a sign;''

a token of war, proclaim war against it, that lives at ease, and is in peace; and so the word is used in the Talmudic language, as Kimchi observes; and to this agrees Jarchi's note,

"to gather against the mountain that is quiet, and trusts in its tranquillity, lift up a banner to the nations.''

Exalt the voice unto them; the Medes, mentioned by name in Isaiah 13:17 such as were within call, or were gathered together by the lifting up of the banner; such were to be urged with great vehemency to enlist themselves, and engage in a war against Babylon:

shake the hand; beckon with it to them that are afar off, that cannot hear the voice:

that they may go into the gates of the nobles; that dwell in the city of Babylon, where they might expect to find rich plunder; though some understand this of the nobles or princes of the Medes and Persians, as Kimchi observes, that should enter through the gates of Babylon into the city; and by others it is interpreted of the soldiers coming to the doors of the leaders or generals of the army, to give in their names, and enlist themselves in their service; which well agrees with what goes before.
