Yom ‘Tzom’ Kippur


Why is Yom Kippur referred to as ‘Yom Tzom Kippur’ in Unetaneh Tokef? Why is it called this exclusively here but not anywhere else?



  1. Whilst it is true that the term Yom Tzom Kippur is not found in Tanach, it is found in the Mishna. It was composed by Rabbi Amnon from Mainz, Germany, in the thirteenth century and it is a much later addition to the the Yamim Noraim liturgy. Rabbi Amnon was a brilliant Torah scholar and he used the Mishna’s description of Yom Kippur.
