Charles Ellicott Commentary Jeremiah 49:9

"If grape-gatherers came to thee, would they not leave some gleaning grapes? if thieves by night, would they not destroy till they had enough?" — Jeremiah 49:9 (ASV)

If grapegatherers come to you ... —The words are reproduced in Obadiah 1:5. Vine-gatherers leave some bunches for the gleaner; robbers are at last satiated with plunder; but the destroyers of Edom would be insatiable . Esau (the name stands for Edom) should be laid bare, and perish utterly. It is significant that there is no promise to Edom that her captivity should be brought back.
