John Calvin's Bible Commentary
Jeremiah 50:33
Our Prophet returns again to his former subject — that God, in destroying the Babylonian monarchy, would have a regard to his chosen people. But the comparison made here is very important; for in the first place, the Prophet refers to an occasion of diffidence and even of despair, which might have closed up the way against all his prophecies. For this objection might have always been made, “We are driven into exile, we are in a far country, and in places distant from one another; it is the same as though we were in another world, and we can hardly move a foot without our conquerors being enraged against us.” Thus the Jews, according to the aspect of things at that time, could not otherwise than despair of returning to their own country. This, then, is the reason why the Prophet says here, by way of concession, “It is, indeed, true that the children of Judah and the children of Israel are oppressed with cruel tyranny:” as when we wish to secure faith, we state what seems to be opposed to us, and then dissipate it; so now the Prophet does in this place, as though he had said, “I see what his own mind may dictate to every one, even that the children of Judah, as well as the children of Israel, are held captive, and shut up by such fastnesses that no way of escape is open to them.”
When he speaks of the children of Israel and of the children of Judah, we must remember that the ten tribes had been led into exile, and also that the whole kingdom had been destroyed; and at length, after a considerable time, the Chaldeans took possession also of the kingdom of Judah. Hence then it was, that both the Israelites and the Jews became subject to a cruel oppression. He therefore adds, They who led them captive have prevailed, or, as some render the last word, “have held them;” for חזק , chesek, means to hold, to lay hold; but the Prophet seems to mean another thing, even that their conquerors so prevailed as securely to rule over them; and hence it is added, they have refused to let them go; and we learn the same thing from the next verse, in which the strength and power of God is set in opposition to the power of their enemies. As far as things appeared to men, there was certainly no way of deliverance for the people. The Prophet then concedes what might have taken away every hope from them.
