Rejoice and be glad, daughter of Edom, that dwell in the land of Uz: The cup shall pass through to you also; you shall be drunken, and shall make yourself naked.
So now in this place our Prophet says, Be glad and rejoice, thou daughter of Edom, who dwellest in the land of Uz By this clause, as I have already said, Jeremiah intimates that the Jews were exposed to the taunts of their enemies, because the Idumeans could now insult them with security. But he immediately adds, also: here he begins a new subject, and this is intimated by the particle גם gam, To thee also shall pass the cup He employs a common metaphor; for adversity is denoted in Scripture by the word cup; for God, according to his will, gives to drink to each as much as he pleases. As when a master of a family distributes drink to his children and servants; so also God, in a manner, extends his cup to every one whom he chastises; nor does he allow any one either to reject the cup offered, or to throw away the wine, but he constrains him to drink and to exhaust to the very dregs as much as he gives to each to drink. Hence it is for this reason that the Prophet says now that the cup would pass over to the Idumeans; for we know that, shortly after, they were subdued by the Chaldeans, with whom they had before been united. But when they had by their perfidy fallen off from their treaty, they were in their turn punished. As, then, the agreement they had made with the Chaldeans did not continue, the Prophet says, that to them also the cup would pass over.
