Shemot 12 discusses the very first commandment given to the nation, the Pesach ritual, highlighting how Hashem directed the Israelites to slaughter a lamb and apply its blood to their doorposts.  What was the purpose of this ritual? (http://alhatorah.org/Purpose_of_the_Pesach) Though, at first glance, it appears to be a protective rite, aimed at saving the Israelites from the Plague of Firstborns, why would Hashem need a sign to distinguish Israelite and Egyptian? How else can the ceremony be understood? This Torahcast, brought to you by ALHATORAH.ORG, featuring Neima Novetsky, explores these questions and more.
