4. And they gave unto Jacob. Though the holy man had his house in suitable subordination; yet as all yielded such prompt obedience to his command by casting away their idols, I doubt not that they were influenced by the fear of danger. Whence also we infer how important it is for us to be aroused from slumber by suffering. For we know how pertinacious and rebellious is superstition. If, in a peaceful and joyous state of affairs, Jacob had given any such command, the greater part of his family would have fraudulently concealed their idols: some, perhaps, would have obstinately refused to surrender them; but now the hand of God urges them, and with ready minds they quickly repent. It is also probable, that, according to the circumstances of the time, Jacob preached to them concerning the righteous judgment of God, to inspire them with fear. When he commands them to cleanse themselves, it is as if he had said, Hitherto ye have been defiled before the Lord; now, seeing that he has regarded us so mercifully, wash out this filth, lest he should again avert his face from us. It seems, however, absurd, that Jacob should have buried the idols under an oak, and not rather have broken them in pieces and consumed them in the fire, as we read that Moses did with the golden calves, (Exodus 32:20,) and Hezekiah with the brazen serpent, (Genesis 18:4.) The fact is not thus related without reason: but the infirmity of Jacob is touched upon, because he had not been sufficiently provident against the future. And perhaps the Lord punished his previous excessive connivance and want of firmness, by depriving him of prudence or courage. Yet God accepted his obedience, although it had some remainder of defect, knowing that it was the design of the holy man to remove idols from his family, and, in token of his detestation, to bury them in the earth. The earrings were doubtless badges of superstition; as at this day innumerable trifles are seen in the Papacy, by which impiety displays itself.
