This week we begin the book of Leviticus with Parashat Vayikra. Leviticus is unique among the books of Torah in that it reads like a manual for the kohanim, the priests of Israel. It lays out the laws of korbanot, or sacrifices. The word korban has as its root the Hebrew letters kuf, bet, and nun. That puts it in the family of Hebrew words having to do with closeness: to draw close, to be close. Sacrifices are the way the ancient Israelites sought to be close to God.
Even though the topic seems dry and far removed from us, you will be surprised at some of the great divrei Torah available on the subject, such as these:
Leviticus on Love by Rabbi Arnold Eisen
Between a Rock and a Hard Place by Rabbi Lance J. Sussman
Invitation to the World by Rabbi Ruth Adar
Generation to Generation? by Rabbi Amy Scheinerman
Thinking about Sacrifice by Rabbi Rachel Barenblat
