Jeremiah 51:58

Her high gates shall be burned with fire. — These were part of the works on which Nebuchadnezzar prided himself as the restorer of the city. The inscription already quoted refers to these as well as to the walls: “Babylon is the refuge of the god Merodach. I have finished Imgur Bel, his great enclosure. In the threshold of the great gates I have adjusted folding-doors in brass.” (Oppert, ut supra; Comp. also Records of the Past, v. pp. 125, 127).

The people shall labour in vain. — The words are all but verbally identical, in some MSS. absolutely so, with those of Habakkuk 2:13. In both the thought is that the stately edifices which had been raised with so much toil by the slave-labour of Nebuchadnezzar’s subjects and captives should all be fruitless. The walls of Babylon are described by Herod. (1, 173), possibly with some exaggeration, as 50 cubits (= 75 feet) thick and 200 high.
