Matthew Poole and continuators on Jeremiah 6:9

9 ¶ Thus saith the LORD of hosts, They shall thoroughly glean the remnant of Israel as a vine: turn back thine hand as a grape-gatherer into the baskets.

Though gleaning be a term proper for all kind of Harvest, yet the word used here is appropriated to the Vintage, and implies the thorough riddance, that the Chaldeans shall make, contrary to the law for gathering the Vintage, tho' it may seem to allude to it, Rev. 19.10. Iudah shall be gleaned over and over, till there be a full end, none left, as the Israelites gleaned the Benjamites, Iudg. 20.45. for thus they picked them up at several times both before 2 King 24.2. and also at the time of Zedekiah's Reign 2 King. 25.6, 7, 11, 18, 19. and this seems to be intimated in the next words. See Hab. 1.9.

As much as to say, they should not be content with one spoiling, but they should go back a second, and a third time, again and again to carry away, both persons and spoil, leaving nothing behind them worth carrying away, chap. 52.28, 29, 30. the first carrying away being as the Vintage, the second the gleaning, carrying away first the principal, and afterwards the more inferiour sort.

As the grape gatherers do, filling one basket after another, whether these be the words of the Babylonians calling upon and stirring up one another to do it, as some; or the words of God to the Babylonians, as most, it comes much to the same thing, for what they did was by Gods Commission.
