Through pride the devil became the devil
Pride goeth before destruction, and an haughty spirit before a fall.
Proverbs 16:18
For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High.
Isaiah 14:13,14
