Genesis 31:13

13. I am the God of Beth-el. It is not wonderful that the angel should assume the person of God: either because God the Father appeared to the holy patriarchs in his own Word, as in a lively mirror, and that under the form of an angel; or because angels, speaking by the command of God, rightly utter their words, as from his mouth. For the prophets are accustomed to this form of speaking; not that they may exalt themselves into the place of God; but only that the majesty of God, whose ministers they are, may shine forth in his message. Now, it is proper that we should more carefully consider the force of this form of expression. He does not call himself the God of Bethel, because he is confined within the limits of a given place, but for the purpose of renewing to his servant the remembrance of his own promise; for holy Jacob had not yet attained to that degree of perfection which rendered the more simple rudiments unnecessary for him. But little light of true doctrine at that time prevailed; and even that was wrapped in many shadows. Nearly the whole world had apostatized to false gods; and that region, nay, even the house of his father-in-law, was filled with unholy superstitions. Therefore, amid so many hindrances, nothing was more difficult for him than to hold his faith in the one true God firm and invincible. Wherefore, in the first place, pure religion is commended to him, in order that, among the various errors of the world, he may adhere to the obedience and worship of that God whom he had once known. Secondly; the promise which he had before received is anew confirmed to him, in order that he may always keep his mind fixed on the special covenant which God had made with Abraham and his posterity. Thus he is directed to the land of Canaan, which was his own inheritance; lest the temporal blessing of God, which he was soon to enjoy, should detain his heart in Mesopotamia. For since this oracle was only an appendix of the previous one, whatever benefits God afterwards bestowed ought to be referred to that first design. We may also conjecture from this passage, that Jacob had before preached to his household concerning the true God and the true religion, as became a pious father of his family. For he would have acted absurdly in uttering this discourse, unless his wives had been previously instructed respecting that wonderful vision. To the same point belongs what he had said before, that the God of his father had brought him assistance. For it is just as if he would openly distinguish the God whom he worshipped from the god of Laban. And now, because he holds familiar discourse with his wives, as on subjects which they know, the conjecture is probable, that it was not Jacob’s fault if they were not imbued with the knowledge of the one God, and with sincere piety. Further, by this oracle the Lord declared that he is always mindful of the godly, even when they seem to be cast down and deserted. For who would not have said that the outcast Jacob was now deprived of all celestial help? And truly the Lord appears to him late; but beyond all expectation shows, that he had never been forgetful of him. Let the faithful, also, at this day, feel that he is the same towards them; and if, in any way, the wicked tyrannically oppress them by unjust violence, let them bear it patiently, until at length, in due time, he shall avenge them.
