Matthew Poole and continuators on Jeremiah 33:4

4 For thus saith the LORD, the God of Israel, concerning the houses of this city, and concerning the houses of the kings of Judah, which are thrown down by the mounts, and by the sword .

That is which in part are thrown down and shall yet further be thrown down, by the engines of War which the Chaldeans use to batter down the City, see before chap. 32.24. some read for the mounts, as if they were thrown down by the Citizens to make room for the Citizens to cast up defensive mounts, the word translated Sword may be as well translated Hammers or Mattocks, as it is 2 Chron. 34.6. it is translated Axes, Ezek. 26.9.
