Lucifier in Isaiah 14

Isaiah 14 vs 12 predicts Lucifer's fate

12 How you have fallen from heaven,
O morning star, son of the dawn!
You have been cast down to the earth,
you who once laid low the nations!

13 You said in your heart,
"I will ascend to heaven;
I will raise my throne
above the stars of God;
I will sit enthroned on the mount of assembly,
on the utmost heights of the sacred mountain. [c]

14 I will ascend above the tops of the clouds;
I will make myself like the Most High."

15 But you are brought down to the grave,
to the depths of the pit.
