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.
The traditional hatred of Edom (the descendants of Esau) against Israel was, in all probability, exhibited by them during Jerusalem's siege and capture by the Chaldeans.   Amos 1:11-12 and the Book of Obadiah make strong references to this hatred.  We may safely conclude that a disaster of such dimensions as the ruin of Jerusalem and the captivity of her people would not have been overlooked by the Edomites as a wonderful opportunity for them to rejoice over the sorrows of the people they hated.
