Albert Barnes Commentary Jeremiah 6:9

"Thus saith Jehovah of hosts, They shall thoroughly glean the remnant of Israel as a vine: turn again thy hand as a grape-gatherer into the baskets." — Jeremiah 6:9 (ASV)

They ... - Each word indicates the completeness of Judah’s ruin.

Turn back your hand - Addressed perhaps to Nebuchadnezzar as God’s servant (Jeremiah 25:9). He is required to go over the vine once again, that no grapes may escape.

Into the baskets - Better, “upon the tendrils.” While the Jews carried captive to Babylon escaped, misery gleaned the rest again and again.
