Thus saith the Lord God,.... Concerning Seir or the Edomites, the prophecy concerning the Moabites being finished:
because that Edom hath dealt against the house of Judah by taking vengeance: or, "revenging a revenge" w; the Edomites bore an old grudge against the Jews, not only because their father Jacob had got the birthright and blessing from their father Esau; but because they were made tributaries to them in David's time, and afterwards severely chastised by Amaziah; these things they laid up in their minds, and vowed revenge whenever they had an opportunity; and now one offered at the destruction of Jerusalem, which they took:
and hath greatly offended, and revenged himself upon them: not only by rejoicing at the destruction of the Jews, but by encouraging the Babylonians in it; assisting them therein, joining with them in plundering the city, and in cutting off those with the sword who endeavoured to make their escape; see Psalms 137:7.
