Num 16:3 They assembled themselves together against Moses and against Aaron and said to them, “You have gone too far! For all in the congregation are holy, every one of them, and the LORD is among them. Why then do you exalt yourselves above the assembly of the LORD?”
This verse occurs in the account of Korah’s rebellion against Moses, ending with the Lord opening up the earth and swallowing Korah and his cohorts. Korah was a full-blown narcissist consumed with jealously for not getting the praise and adoration he just knew he was entitled to. Well, he got what he was entitled to in the end!
The following link is to a short video by Dr. Les Carter who has a youtube channel focused on the issue of narcissism. It is very good. I highly recommend that you listen to this (only 14 minutes). It is a real help.
