Even on Holidays and Festivals, of which it is written : "And you shall rejoice before the Lord your God" (Deut. 12:18), one should not prolong his drinking more than is proper, as it is said : "Because you did not serve the Lord your God with joyfulness and with gladness of heart" (Ibid. 28:47). From this you learn that we have not been commanded to rejoice in a manner that the Creator of all is forgotten. For it is impossible to serve the Lord, may He be Blessed, out of light headedness, or laughter, or drunkenness.
