John Calvin's Bible Commentary
Jeremiah 43:8
This passage shews that the Prophet was by force drawn away with others, so that he became an exile in Egypt contrary to his own wishes; for he did not go there of his own accord, inasmuch as we have seen how strictly he forbade them all to go down to Egypt. He was, however, compelled to go there, as though he had been bound with chains. He did not then go there designedly, nor did he through despair follow those miserable men; for he would have preferred to die a hundred times through famine and want in the land of Judah rather than to have sought in this way the lengthening of his life. It then appears that he was driven there as it were by enemies.
But as nothing happens except through God’s purpose, so from this prophecy it appears that God ordered the going down of his servant, and that he was not so subjected to the will of the wicked, but that he was always guided by the hidden influence of God; for it was God’s will to have his herald even in the midst of Egypt, that he might declare to the Jews what, was to be. His doctrine, indeed, was not of any benefit to them; but it was God’s purpose to drive them as it were into madness, inasmuch as their wickedness was wholly irreclaimable; for it is a harder thing for the wicked to hear God’s voice when he threatens vengeance, than to feel his hand. When, therefore, the unbelieving avoid the word of God, they are still constrained, willing or unwilling, to hear what they willfully reject, even that God will be their judge. The Prophet then was sent, according to the hidden purpose of God, into Egypt, that he might there perform his wonted vocation and proceed in the discharge of his office, and there carry on his prophetic work.
But this prophecy was greatly disliked; for as the Jews had been already much exasperated, this threatening was still more calculated to kindle up their fury; and Jeremiah did also create danger to himself from the Egyptians, for he not only threatened the Jews, but also the whole kingdom of Egypt. We hence perceive how invincible was his courage, for he marched through certain deaths, and was yet terrified by no dangers, but performed the office entrusted to him by God. Some think that he was on this account stoned by the Jews; but this is not probable, nay, it may be gathered from other places that he died a natural death. However this may have been, his perseverance and firmness were wonderful, for he struggled to the end, and without weariness, with those wild beasts, whose savageness he had more than enough experienced.
Let us now see what this prophecy is: The word of Jehovah came to Jeremiah; and the sum of it is, that the Prophet was bidden not only to proclaim the vengeance of God, but also to confirm it by a visible symbol, as it was necessary to arouse unbelieving men. For so great was their stupidity, that unless God roused all their senses, they would have never attended; they were deaf. Then the Lord set before their eyes what they were unwilling and refused to hear. For this reason the Prophet was bidden to add an outward sign to his prophecy; according to what we have stated in other places, signs were often connected with the doctrine on account of the tardiness, or rather the stupidity of men.
