Various laws of Tumah.
Can a Kohen walk by a non-Jewish cemetery? Does Tumah spread under umbrellas? What about thin branches, twigs, and leaves?
Why is it prohibited for a Kohen to come in contact with a Met?
The mitzvah of gid hanosheh forbids us from eating the sciatic nerve, a sinew that runs from the lower back over the top of the hip and down the leg.
Another Mitzvah is not eating the Cheylev, some fats in an animal.
