meaning of the breaking of the glass at a jewish wedding
Jewish wedding The origin of this custom is unknown, although many reasons have been given. The primary reason is that joy must always be tempered.[25] This is based on two accounts in the Talmud of rabbis who, upon seeing that their son's wedding celebration was getting out of hand, broke a vessel – in the second case a glass – to calm things down. Another explanation is that it is a reminder that despite the joy, Jews still mourn the destruction of the Temple in Jerusalem. Because of this, some recite the verses "If I forget thee / O Jerusalem..." (Ps. 137:5) at this point.[15] Many other reasons have been given by traditional authorities.[25]
