Charles Ellicott 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)

Turn back thine hand. —The image of the grape-gatherer carrying on his work to the last grape or tendril was a natural parable of unsparing desolation. The command is addressed to the minister of destruction, Nebuchadnezzar, or, it may be, to the angel of death.

Into the baskets. —The noun is found here only, and probably means, like a kindred word in Isaiah 18:5, the tendrils of the vine upon which the hand of the gatherer was to be turned.
