John Calvin's Bible Commentary
Jeremiah 50:1
Our Prophet has been hitherto speaking of neighboring nations who had cruelly harassed the chosen people; and it was some consolation when the children of Abraham understood that God undertook their cause and would be the avenger of those wrongs which they had suffered. But this of itself would have been no great consolation, yea, it might have been viewed as nothing by many, while there was no hope of restoration; for it would have been but a small consolation to have others as associates in misery. If, indeed, Jeremiah had only taught that none of the nations who had troubled God’s Church would escape unpunished, the Jews might have raised an objection, and said, that they were not freed from their own calamities, because the monarchy of Babylon still flourished, and that they were buried as it were in a perpetual grave. It was therefore necessary that what we read here should be predicted. And though this prophecy is given last, we ought to notice that the Prophet had from the beginning expressly spoken, as we have seen, of the calamity and destruction of Babylon. But this prophecy is given as the conclusion of the book, to mitigate the sorrow of the miserable exiles; for it was no small relief to them to hear that the tyranny by which they were oppressed, and under which they did live as it were a lifeless life, would not be perpetual. We now then understand why the Prophet spoke of the Babylonians and of their destruction.
But a longer preface would be superfluous, because those acquainted with Scripture well know that the Jews were at length so reduced by the Babylonians that their very name seemed to have been obliterated. As then they were reduced to such extremities, it is no wonder that the Prophet here affirms that the Babylonians would be at length punished, and that not only that God might show himself to be the avenger of wickedness, but also that the miserable exiles might know that they were not wholly repudiated, but on the contrary that God had a care for their salvation. We now perceive the design of this prophecy.
The word of Jehovah, he says, which he spoke concerning Babylon, concerning the land of the Chaldeans, by the hand of Jeremiah the Prophet He testifies in his usual manner that he did not bring forward what he himself had invented, but that God was the author of this prophecy. He at the same time declares that he was God’s minister; for God did not descend from heaven whenever it pleased him to reveal his favor to the Jews, but, as it is said in Deuteronomy, he was wont to speak by his servants. (Deuteronomy 18:18.) In short, Jeremiah thus recommends the things he was about to say, that the Jews might reverently receive them, not as the fictions of men, but as oracles from heaven. It follows —
