Biblical Personalities: Moshe’s Parah
Moshe performed the first Parah Aumah on the 2nd of Nisan (Gittin 60b) The Holy One, Blessed is He, looked for a merit with which to redeem Israel, but found nothing other than the merit of Moses and Aaron, and it stood by them (Shemot Rabbah 15:3) It is this same merit that gives life to the ashes of Moshe’s Parah, which will be mixed with the ashes of the Parah brought by the Messiah.
