The selection of this one neighbour of the Jews for special attention is accounted for by what contemporary prophets tell us concerning the behaviour of the Edomites when Jerusalem fell. They flew like vultures to a carcass. Ezekiel writes: "Thus saith the Lord God, Because that Edom hath dealt against the house of Judah by taking vengeance, and hath greatly offended, and revenged himself upon them; therefore thus saith the Lord God, I will stretch out Mine hand upon Edom, and will cut off man and beast from it, and I will make it desolate from Teman; even unto Dedan shall they fall by the sword. And I will lay My vengeance upon Edom by the hand of My people Israel, and they shall do in Edom according to Mine anger and according to My fury, and they shall know My vengeance, saith the Lord God."[263] Isaiah xxxiv. is devoted to a vivid description of the coming punishment of Edom. This race of rough mountaineers had seldom been on friendly terms with their Hebrew neighbours. Nations like individuals, do not always find it easy to avoid quarrels with those who are closest to them. Neither blood relationship nor commerce prevents the outbreak of hostilities in a situation that gives many occasions for mutual jealousy. For centuries France and England, which should be the best friends of proximity generated friendship, regarded one another as natural enemies. Germany is even a nearer neighbour to France than England is, and the frontiers of the two great nations are studded with forts. It does not appear that the extension of the means of communication among the different countries is likely to close the doors of the temple of Janus. The greatest problem of sociology is to discover the secret of living in crowded communities among a variety of conflicting interests without any injustice, or any friction arising from the juxtaposition of different classes. It is far easier to keep the peace among backwoodsmen who live fifty miles apart in lonely forests. Therefore it is not a surprising thing that there were bitter feuds between Israel and Edom. But at the time of the Babylonian invasion these had taken a peculiarly odious turn on the side of the southern people, one that was doubly offensive. The various tribes whom the huge Babylonian empire was swallowing up with insatiable greed should have forgotten their mutual differences in face of their common danger. Besides, it was a cowardly thing for Edom to follow the example of the Bedouin robbers, who hovered on the rear of the great armies of conquest like scavengers. To settle old debts by wreaking vengeance on a fallen rival in the hour of her humiliation was not the way to win the honours of war. Even to a calm student of history in later ages this long-past event shews an ugly aspect. How maddening must it have been to the victims! Accordingly we are not astonished to see that the doom of the Edomites is pronounced by Hebrew prophets with undisguised satisfaction.
