He uses nearly the same words respecting Tyrus which he did respecting Gaza, and charges it with the same sin, which was that of removing the Jews from their country, as refugees and exiles, into Idumea, and of selling them as captives to the Idumeans. As of all the rest, he declares the same of Tyrus, that they had not lightly sinned, and that therefore no moderate chastisement was sufficient; for they had for a long time abused God’s forbearance, and had become stubborn in their wickedness.
But what he says, that they had not been mindful of the covenant of brethren, some refer to Hiram and David; for we know that they had a brotherly intercourse, and called each other by the name of brothers; so great was the kindness between them. Some then think that the Tyrians are here condemned for having forgotten this covenant; for there ought to have remained among them some regard for the friendship which had existed between the two kings. But I know not whether this is too strained a view: I rather incline to another, and that is, that the Syrians delivered up the Jews and the Israelites to the Idumeans, when yet they knew them to be brethren: and they who implicate themselves in a matter of this kind are by no means excusable. When I see one conspiring for the ruin of his own brother, I see a detestable and a monstrous thing; if I abhor not a participation in the same crime, I am involved in the same guilt. When therefore the Syrians saw the Idumeans raging cruelly against their brethren, for they were descended from the same family, they ought doubtless to have shown to the Idumeans how alienated they were from all humanity and how perfidious they were against their own brethren and relatives. Now the Prophet says, that they had been unmindful of the covenant of brethren, because they made themselves assistants in so great and execrable a crime as that of carrying away Jews into Idumea, and of shutting them up there, when they knew that the Idumeans sought nothing else but the entire ruin of their own brethren. This seems to be the real meaning of the Prophet.
