(3) I will encamp against thee . . .--The words describe the strategy of an Eastern siege, as we see it in the Assyrian sculptures--the mound raised against the walls of the city, the battering-ram placed upon the mound, and brought to bear upon the walls. (See Jeremiah 33:4; Ezekiel 4:2.)

Verse 3. - I will camp against thee round about; i.e. "I will bring armed men against thee who shall encamp around the entire circuit of thy walls." There was small chance of forcing an entrance into Jerusalem on any side except the north; but, order to distress and harass her, an enemy with numerous forces would dispose them all round the walls, thus preventing all ingress or egress (see Luke 19:43). And... lay siege against thee with a mount; or, with a mound. Artificial mounds were raised up against the walls of cities by the Assyrians, as a foundation from which to work their battering rams with greater advantage against the upper and weaker portion of the defenses (see 'Ancient Monarchies,' vol. 2. p. 80). And... raise forts against thee. "Forts" were usually movable, and accompanied the battering-ram for its better protection. Archers in the forts cleared the walls of their defenders, while the ram was employed in making a breach (see Layard, 'Monuments of Nineveh,' Second Series, p. 21).

29:1-8 Ariel may signify the altar of burnt-offerings. Let Jerusalem know that outward religious services will not make men free from judgements. Hypocrites never can please God, nor make their peace with him. God had often and long, by a host of angels, encamped round about Jerusalem for protection and deliverance; but now he fought against it. Proud looks and proud language shall be brought down by humbling providences. The destruction of Jerusalem's enemies is foretold. The army of Sennacherib went as a dream; and thus the multitudes, that through successive ages fight against God's altar and worship, shall fall. Speedily will sinners awake from their soothing dreams in the pains of hell.And I will camp against thee round about,.... Or as a "ball" or "globe" (o); a camp all around; the Lord is said to do that which the enemy should do, because it was by his will, and according to his order, and which he would succeed and prosper, and therefore the prophecy of it is the more terrible; and it might be concluded that it would certainly be fulfilled, as it was; see Luke 19:43,

and will lay siege against thee with a mount: raised up for soldiers to get up upon, and cast their arrows into the city from, and scale the walls; Kimchi and Ben Melech interpret it a wooden tower. This cannot be understood of Sennacherib's siege, for he was not suffered to raise a bank against the city, nor shoot an arrow into it, Isaiah 37:33 but well agrees with the siege of Jerusalem by the Romans, as related by Josephus (p):

and I will raise forts against thee; from whence to batter the city; the Romans had their battering rams.
