Aliya Summary: We are enjoined not to consume blood. When slaughtering fowl or undomesticated animals, we are commanded to cover their blood with earth. The Jews are admonished not to follow the depraved ways of the Egyptians and Canaanites. On this note, the Torah provides a list of prohibited sexual relationships. The list includes adultery, cohabiting with a menstruating woman, and forbidden close relatives.
From the term “and live by them”, we are taught two important concepts. Judaism is not just a religion; it is a way of life. Furthermore, this verse is (one of) the source(s) of the concept that many mitzvot (but not all!) are pushed aside if there is a life-threatening situation. Mitzvot are to LIVE by, not die by.
