Jeremiah 6:9

The heads of this paragraph are the very same with those of the last; for precept must be upon precept and line upon line. I. The ruin of Judah and Jerusalem is here threatened. We had before the haste which the Chaldea army made to the war (Jer 6:4, Jer 6:5); now here we have the havoc made by the war. How lamentable are the desolations here described! The enemy shall so long quarter among them, and be so insatiable in their thirst after blood and treasure, that they shall seize all they can meet with, and what escapes them at one time shall fall into their hands another (Jer 6:9): They shall thoroughly glean the remnant of Israel as a vine; as the grape-gatherer, who is resolved to leave none behind, still turns back his hand into the baskets, to put more in, till he has gathered all, so that they be picked up by the enemy, though dispersed, though hid, and none of them shall escape their eye and hand. Perhaps the people, being given to covetousness (Jer 6:13), had not observed that law of God which forbade them to glean all their grapes (Lev 19:10), and now they themselves shall be in like manner thoroughly gleaned and shall either fall by the sword or go into captivity.

The Jews are the grapes, their enemies the unsparing gleaners. turn back . . . hand--again and again bring freshly gathered handfuls to the baskets; referring to the repeated carrying away of captives to Babylon (Jer 52:28-30; Kg2 24:14; Kg2 25:11).
