John Calvin Commentary Jeremiah 25:37

"And the peaceable folds are brought to silence because of the fierce anger of Jehovah." — Jeremiah 25:37 (ASV)

He continues with the same subject: that the tents, previously tranquil, would perish or be destroyed. And he intentionally calls their dwellings peaceable; for the Jews, having found that their enemies had not previously disturbed them, still promised themselves the same good fortune in the future.

And the faithful indeed rightly act in this way, and justly conclude from God’s previous benefits that he will be kind to them as he had always been; but hypocrites, though they do not repent, yet absurdly think that God is bound to them; and though they daily provoke his wrath, they still securely continue in their confidence of having peace. Since God then had until that time deferred the grievousness of his wrath, the Prophet says that, though their tents had been peaceable, they still could not be exempted from destruction as soon as the indignation of God’s wrath went forth. It might have been enough to use one of these words, either of חרון, cherun, or of אף, aph; but the Prophet used the two, indignation and wrath, so that he might fill the wicked with more terror; for as they were obstinate in their wickedness, so they were not moved unless God doubled his strokes and set forth the extremity of his wrath.
