(53) Though Babylon should mount up to heaven . . .--The special form of the phrase recalls the language of the builders of the Tower which made the name of Babylon conspicuous (Genesis 11:4). Even though that boastful attempt should be realised, Jeremiah says, it should prove a vain defence. As it was, the walls of Babylon which Nebuchadnezzar had built were of enormous height. Greek writers, possibly speaking of different walls (as there were two lines of fortifications), give from 75 to 335 feet. Nebuchadnezzar, in one of his inscriptions, records their greatness in words that remind us of Daniel 4:30. "To make more difficult the attack of an enemy against Imgur Bel, the indestructible wall of Babylon, I constructed a bulwark like a mountain" (Oppert, Exped. en Mesop., i. p. 230; Records of the Past, v. p. 131).

Verse 53. - The height of her strength; i.e. her lofty walls and towers.

51:1-58 The particulars of this prophecy are dispersed and interwoven, and the same things left and returned to again. Babylon is abundant in treasures, yet neither her waters nor her wealth shall secure her. Destruction comes when they did not think of it. Wherever we are, in the greatest depths, at the greatest distances, we are to remember the Lord our God; and in the times of the greatest fears and hopes, it is most needful to remember the Lord. The feeling excited by Babylon's fall is the same with the New Testament Babylon, Re 18:9,19. The ruin of all who support idolatry, infidelity, and superstition, is needful for the revival of true godliness; and the threatening prophecies of Scripture yield comfort in this view. The great seat of antichristian tyranny, idolatry, and superstition, the persecutor of true Christians, is as certainly doomed to destruction as ancient Babylon. Then will vast multitudes mourn for sin, and seek the Lord. Then will the lost sheep of the house of Israel be brought back to the fold of the good Shepherd, and stray no more. And the exact fulfilment of these ancient prophecies encourages us to faith in all the promises and prophecies of the sacred Scriptures.Though Babylon should mount up to heaven,.... Could the walls of it, which were very high, two hundred cubits high, as Herodotus (p) says, be carried up as high as heaven; or the towers of it, which were exceeding high, ten foot higher than the walls, as Curtius (q) says, likewise be raised to the same height:

and though she should fortify the height of her strength: make her walls and towers as strong as they were high; unless this is to be understood particularly of the temple of Bel, in which was a solid tower, in length and thickness about six hundred and sixty feet; and upon this tower another; and so on to the number of eight, towers; and in the last of them a large temple, as the above historian (r) relates: but if these towers could have been piled up in a greater number, even so as to reach to heaven, it would have availed nothing against the God of heaven, to secure from his vengeance. The Targum is,

"if Babylon should be built with buildings as high as heaven, and should fortify the strong holds on high:''

yet from me shall spoilers come, saith the Lord; the Medes and Persians, sent and commissioned by him, who would pull down and destroy her walls and towers, be they ever so high and strong.
