There's a line that has made its way into a number of songs:
כל המשמח חתן וכלה זוכה בחמישה קולות
Anyone who gladdens the groom and bride will merit five voices.
But the source Gemara (Brachos 6B) is more specific:
וא"ר חלבו א"ר הונא: כל הנהנה מסעודת חתן ואינו משמחו עובר בחמישה קולות ... ואם משמחו מה שכרו? אמר רבי יהושע בן לוי זוכה לתורה שנתנה בחמישה קולות
[...] anyone who enjoys the feast of a groom and does not gladden him violates five voices [...] And if he does, what is his reward?[...] he merits the Torah, which is given with five voices.
So we only see that it's about the groom, not about the bride. Furthermore, the merit one receives is the Torah, not the five voices.
- What is the source of its popular formulation?
- If it is not a reputable halachic source, where do we see that one should gladden the bride?
