Obadiah 1:11

In the day thou stoodest on the other side,.... Aloof off, as a spectator of the ruin of Jerusalem, and that with delight and pleasure; when they should, as brethren and neighbours, have assisted against the common enemy; but instead of this they stood at a distance; or they went over to the other side, and joined the enemy, and stood in opposition to their brethren the Jews:in the day that the strangers carried away captive his forces; that is, at the time that the Chaldeans took Jerusalem, and carried captive as many of the forces of the Jews as fell into their hands; or when"the people spoiled his substance,''as the Targum; plundered the city of all its wealth and riches:and foreigners entered into his gates; the gates of their cities, particularly Jerusalem; even such who came from a far country, the Babylonians, who were aliens and strangers from the commonwealth of Israel; whereas the Edomites were their near neighbours, and allied to them by blood, though not of the same religion; and by whom they helped against a foreign enemy, instead of being used by them as they were:and cast lots upon Jerusalem; either to know when they should make their attack upon it; or else, having taken it, the generals of the Chaldean army cast lots upon the captives, to divide them among them, so Kimchi; see Joe 3:3; or rather, the soldiers cast lots for the division of the plunder of the city, as was usual at such times:even thou [wast] as one of them; the Edomites joined the Chaldeans, entered into the city with them, showed as much wrath, spite, and malice, as they did, and were as busy in dividing the spoil.
