Matthew Poole and continuators on Jeremiah 25:28

28 And it shall be if they refuse to take the cup at thine hand to drink, then shalt thou say unto them, Thus saith the LORD of hosts, Ye shall certainly drink .

The meaning of these two verses is no more then this, God let Ieremiah in a Vision know that it was his will, that he should prophesie a certain, and inavoidable ruine to all these Nations, which was brought upon all the rest by the King of Babylon, whom God made his instrument to execute his vengeance upon them: and last of all upon the King of Babylon himself by Cyrus the King of Persia. This judgment which he telleth them should be by the Sword, he expresseth by the effects, falling and rising no more, and commands them to drink it to comport, with the metaphor of the Wine cup of Gods fury, mentioned ver. 15. The drinking of cups of heady intoxicating Wine ordinarily producing such effects, as [illegible: 1 letter]puing and falling, &c. This cup of the Lords fury he assures them, they should not turn by, but should most certainly drink it.
