Isaiah 14:12-14 (KJV):

¹²How art thou fallen from heaven, O Lucifer, son of the morning! 
How art thou cut down to the ground, which didst weaken the nations!

¹³For 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: 

¹⁴I will ascend above the heights of the clouds; I will be like the most High.
