Leviticus 20 - Introduction
INTRODUCTION TO LEVITICUS 20
In this chapter several laws are, repeated, enforced with a penalty annexed to them, and the breach them made capital, to deter from it, as giving seed to Molech, Leviticus 20:1; going after such that have familiar spirits, or are wizards, Leviticus 20:6; by shunning which, and other sins, a regard would be shown to holiness, Leviticus 20:7; such as cursing parents, Leviticus 20:9; committing adultery, Leviticus 20:10; incestuous copulations, and marriages, and beastly actions, Leviticus 20:11; all which it became the Israelites to avoid, lest, when come into the land of Canaan, they should be cast out of it, as the old inhabitants were for the same things, Leviticus 20:22; and therefore, that they might appear to be a distinct people from others, they were to put a difference between clean and unclean creatures, Leviticus 20:25; and the chapter is closed with a law, making it death for any person to have a familiar spirit, or to be a wizard, Leviticus 19:27.
