Now when he says, If they go into captivity among their enemies, I will there command the sword to slay them, some interpreters confine this part to that foolish flight, when a certain number of the people sought to provide for their safety by going down into Egypt. Johanan followed them, and a few escaped, (Jeremiah 43:2) but according to what Jeremiah had foretold, when he said, ‘Bend your necks to the king of Babylon, and the Lord will bless you; whosoever will flee to Egypt shall perish;’ so it happened: they found this to be really true, though they had ever refused to believe the prediction. Jeremiah was drawn there contrary to the wish of his own mind: he had, however, pronounced a curse on all who thought that it would be an asylum to them. But the Lord permitted him to be drawn there, that he might to his last breath pronounce the Woe, which they had before heard from his mouth. But I hardly dare thus to restrict these expressions of the Prophet: I therefore explain them generally, as meaning, that exile, which is commonly said to be a civil death, would not be the end of evils to the Israelites and to the Jews; for even when they surrendered themselves to their enemies, and suffered themselves to be led and drawn away wherever their enemies pleased, they could not yet even in this way preserve their life, because the Lord would command the sword to pursue them even when exiles. This, in my view, is the real meaning of the Prophet.
He at last subjoins, I will set my eyes on them for evil, and not for good. There is a contrast to be understood in this clause: for the Lord had promised to be a guardian to his people, according to what is said in Psalms 121:4,
‘Behold, he who guards Israel neither sleeps nor slumbers.’
As hypocrites ever lay hold on the promises of God without repentance and faith, without any religious feeling, and afterwards turn them to support their vain boasting, the Prophet therefore says here, that the eye of God would be upon them, not indeed in his wonted manner to protect them, as he had done from the beginning, but, on the contrary, to accumulate punishment on punishment: it was the same thing as though he said, “As I have hitherto watched over the safety of this people, whom I have chosen for myself, so I will hereafter most sedulously watch, that I may omit no kind of punishment, until they be utterly destroyed.”
And this sentence deserves to be specially noticed; for we are reminded, that though the Lord does not indeed spare unbelievers, he yet more closely observes us, and that he will punish us more severely, if he sees us to be obstinate and incurable to the last. Why so? Because we have come nearer to him, and he looks on us as his family, placed under his eyes; not that anything is hid or concealed from him, but the Scripture speaks after the manner of men. While God then favors his people with a gracious look, he yet cannot endure hypocrites; for he minutely observes their vices, that he may the more severely punish them. This then is the substance of the whole. It follows —
