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.

gates—one hundred in number, of brass; twenty-five on each of the four sides, the city being square; between the gates were two hundred and fifty towers. Berosus says triple walls encompassed the outer, and the same number the inner city. Cyrus caused the outer walls to be demolished. Taking the extent of the walls to be three hundred and sixty-five stadia, as Diodorus states, it is said two hundred thousand men completed a stadium each day, so that the whole was completed in one year.
labour … in the fire—The event will show that the builders of the walls have "labored" only for the "fire" in which they shall be consumed, "In the fire" answers to the parallel, "burned with fire." Translate, "shall have labored in vain," &c. Compare Job 3:14, "built desolate places for themselves," that is, grand places, soon about to be desolate ruins. Jeremiah has in view here Hab 2:13.
