Jeremiah 25:17 - Joseph Benson’s Commentary on the Old and New Testaments

Then took I the cup It is not to be imagined that Jeremiah went round in person to all the nations and kings here enumerated, with a cup of wine in his hand, but, doubtless, what is here related passed in a vision, in which it was represented to his view. This, either by writing, or by some special messenger, he communicated to the several kings and nations to which God ordered him to publish it. Or, he himself actually did what is figuratively designed, that is, he publicly announced the judgments of God severally against them, as we find in the Chapter s mentioned in the note on Jeremiah 25:13.
