Leviticus 21:1 - 24:23
Realms of clean and unclean... What is unclean? Why are they unclean? How do we get clean? How do we stay clean?
What are the spiritual meanings behind the physical instructions? Can we be spiritually unclean? Can we be clean again?
The Book of Education (Sefer HaChinuch, circa 1300) elucidates the purpose of counting the omer. "The entire basis of the Jewish people's existence is only for Torah. And all of existence was created for Torah. This was the reason for the redemption and exodus from Egypt - so that we would receive the Torah at Sinai. Therefore we were commanded to count from Passover until Shavuot to display our excitement and anticipation towards the Day of the Giving of the Torah. We long for that day like a slave longs and counts the days until he will be free."
