Malachi 1:1-3

"Objectors here allege that this covenant and its decree referred to Canaan, on which the Prophet Malachi dwells (Mal. 1.1-3). And, indeed, this objection might be worthy of notice if God had designed merely to fatten the Jews in Canaan as pigs in a sty. But the mind of the prophet is very different from this. God had promised that land to Abraham as an outward symbol or figure of a better inheritance, and had given it to Abraham's posterity for a possession, that He might there collect them together as a peculiar people unto Himself, and might there erect a sanctuary of His presence and grace. These great ends and objects are those which the prophet is revolving in his deep and reflective mind. In a word, the prophet is holding Canaan to be the sacred habitation of God. And as Esau was deprived of this habitation, the prophet sacredly gathers that he was hated of God, because he had been thus rejected from the holy and elect family, on which the love of God perpetually rests. We also, with the prophet, must carefully consider the particular nature of that land, and the peculiar quality which God assigns to it, that it might be a certain earnest or pledge of that spiritual covenant which God entered into with the seed of Abraham. It is in full sacred point, therefore, that the apostle records that the free election of God fell upon Jacob, because, being yet unborn, he was appointed to enjoy the inheritance, while his brother was, at the same time, rejected. But Paul is proceeding much father still in his sacred argument, and maintaining that this inheritance was not obtained by works, nor conferred on Jacob from any respect to works which he should in his after life perform. Nor is even this all. The apostle expressly declares that the brothers were thus separated, and this difference made between them, before either of them had done any one thing good or evil. From these facts the apostle solemnly settles it, that the difference made between the children was not from any works whatever, but from the will of Him that called."
