John Calvin's Bible Commentary
Jeremiah 50:28
The Prophet again shows, that God in punishing Babylon, would give a sure proof of his favor towards his Church. For this prophecy would have been uninteresting to the faithful, did they not know that God would be an enemy to that great monarchy, because he had undertaken the care of their safety. Then the Prophet often calls the attention of the faithful to this fact, that God’s vengeance on the Babylonians would be to them a sure proof of God’s favor, through which he had once embraced them, and which he would continue to show to them to the end.
This, then, was the design of the Prophet, when he said, The voice officers and of those who escape from the land of Babylon, etc.; as though he had said, “Babylon is on many accounts worthy of destruction, but God in destroying it will have a regard to his own people, and will effectually show that he is the Father of the people whom he has adopted.” Jeremiah afterwards exhorts the faithful to show their gratitude. There are here, then, two things; the first is, that when God destroyed Babylon, the people would hence with certainty perceive how dear they were to God; and secondly, from this truth flows an exhortation, that the faithful were not to be mute at such a singular benefit of God, but were to proclaim their deliverance. Hence he says, The voice of fleers and of those who escape from the land of Babylon, to announce in Sion, etc. By saying in Sion, he shows for what end God intended to gather his people, even that he might again be worshipped as formerly-in his own Temple.
He adds, to announce in Sion the vengeance of our God The vengeance of God is to be taken here in an active sense, signifying the vengeance which God would execute. The vengeance of the Temple, which immediately follows, is to be taken passively, as meaning the vengeance by which God would avenge the indignity offered to the Temple. God then takes vengeance, and God’s Temple is defended from contempt and reproach.
We now then see the meaning of this passage. The Prophet first teaches us, that God would have a regard to his people in so rigidly punishing Babylon; and secondly, he adds an exhortation, lest the faithful should be unthankful to God, but acknowledge that God, for the sake of their deliverance had undertaken war against that monarchy; and lastly, he shows the end, even that the people who had been scattered, as it is said in Psalms 147:2,
“God is he who gathers the dispersed of Israel,”
might again be collected together. As, then, the Jews were as a mutilated body among the Chaldeans, the Prophet shows that that monarchy would be dispersed, in order that the faithful might again be gathered, and that all might worship God together in the Temple, or on mount Sion. It follows, —
