In their heat I will make their feasts— I will give them their cup when they are now heated, and I will make them drunken, that they may be sick, and sleep, &c. "While they are feasting themselves, I will provide them another cup to drink; namely, that of my fury and indignation." See the note on Jeremiah 51:7. It is very well known, that Babylon was taken on a night of public rejoicing, in honour of the goddess Sheshach, mentioned in the next note.
