כּוֹס־זָהָ֤ב בָּבֶל֙ בְּיַד־יְהוָ֔ה מְשַׁכֶּ֖רֶת כָּל־הָאָ֑רֶץ מִיֵּינָהּ֙ שָׁת֣וּ גוֹיִ֔ם עַל־כֵּ֖ן יִתְהֹלְל֥וּ גוֹיִֽם׃
Rashi on Jeremiah
a golden cup Until now, Babylon was [a golden cup] in the Lord’s hand with which to intoxicate the whole earth with the wine of wrath.
Rashi on Jeremiah
therefore, nations are mad They have become drunk and have become mad.
