In parshat Shemini: Following the seven days of their inauguration, Aaron and his sons begin to officiate as kohanim (priests). Aaron’s two elder sons, Nadav and Avihu, offer a “strange fire before G‑d” and die. Aaron is silent in face of his tragedy. G‑d commands the kosher laws, identifying the animal species permissible and forbidden for consumption. Also in Shemini are some of the laws of ritual purity.
Here’s a collection of Torah Talks from previous years on Parshat Shemini.
