Leviticus 20 parallel’s chapter 18 in most ways. They both deal with those things that profane the people and the land. They both respond to sexual sins and blatant ungodliness. Both refer to the corruption of the nation through the corruption of the people, and that the very land itself will spew them out when their actions come out this way.
All of this is important for all people. These are sins that cause the land to become unfertile and to reject its inhabitants, whether they be Christians, or Muslims, or Jews, or Hindu’s, or Buddhists, or Atheists, or Animists, any others. When we pursue sexual immorality and spiritists, we will find time and time again that our nations will become more and more corrupt and that we will lose what we cherish most.
On a more positive note, in this chapter we come across a new name of God; YHWH Qadash. YHWH Qadash appears in verse 8, and it means the LORD (YHWH) who sanctifies you. It is a beautiful picture of how YHWH cherishes His people and sets them apart for Himself. Those who are His children are blessed and honored by His name and His work in and through us. We are pursued and set apart by the Most Holy God. It is both an honor and a responsibility, and it must not be taken lightly. It must not be profaned.
