Rashi
your wine is diluted with water Your drinks are mixed with water, as is stated in Pesikta (122b). [The word] means ‘mixed,’ although there is no similar word in Scripture to prove it, but the Midrash Aggadah explains (Ecc. 2:2): “Of laughter I said, it makes one mad (מְהוֹלָל)” to mean that it is confused, or mixed up.
