Leviticus 12:1 - 15:33
Isaiah 66:1 - 66:24
In the Torah portion Tazria, God instructs Moses about the purification rituals for mothers following childbirth. God then describes to Moses and Aaron the procedures for identifying and responding to those infected with leprosy. In Metzora, God describes the purification ritual for people and homes afflicted with skin diseases; God also instructs Moses and Aaron regarding the laws of the emission of bodily fluids.
These two Torah portions describe in hyper-focused detail a spectrum of infections and the spiritual methods of remedying them.
