The Sharia of Moses in the TORA
Part 1 - The 248 Positive Commandments of the Tora
54 - REJOICING ON THE FESTIVALS
The words, you shall rejoice in your feast, include the further injunction of the sages that the Jews are to rejoice by all possible modes of rejoicing, as by eating meat on the festivals, drinking wine, putting on new garments, distributing fruits and sweetmeats to children and women, and making merry with musical instruments and dancing in the sanctuary. However, the most binding of these modes of rejoicing is the drinking of wine, because that is specially associated with rejoicing.
