READING: Leviticus 15
This chapter talks more about the illnesses that make a person unclean. These are illnesses that result in a discharge. Note that the illnesses required that a sin and a burnt offering be made after the person was well (just like in the previous chapters). The natural secretions in verses 16-24, however, did not require any offerings.
These chapters make me very thankful that we live in the age of modern medicine! Many of the illnesses mentioned in these chapters can easily be treated today. We don't have to wait them out like they did back then. God has given man the ability to figure out a lot about how the human body works. (But they have only scratched the surface.)
There's a related story in Mark 5:25-34.
