By the hand of my people Israel. — This points distinctly to the fact that the Divine vengeance on Edom should be accomplished by the hand of the Israelites, a prophecy which was fulfilled when they were conquered by John Hyrcanus, and compelled to submit to circumcision as a mark of absorption into the Jewish people. Subsequently Herod (who was himself of Idumean origin), as king of the Jews, reigned over them, and their name disappeared from history.
Many commentators would see in this prophecy a further intimation of their ultimate conversion and incorporation into the Church; but this seems quite foreign, not only to the scope of this series of prophecies, but especially to the connection, “I will lay my vengeance upon Edom,” and “they shall know my vengeance.”
