Shabbat Parah / שבת פרה

Shabbat Parah ("Sabbath [of the] red heifer" שבת פרה) takes place on the Shabbat before Shabbat HaChodesh, in preparation for Passover. Numbers 19:1-22 describes the parah adumah ("red heifer") in the Jewish temple as part of the manner in which the kohanim and the Jewish people purified themselves so that they would be ready ("pure") to sacrifice the korban Pesach.
