The only time the name “Lucifer” is mentioned in the Bible is in Isaiah 14:12.

How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!Isaiah 14:12 (KJV)

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!Isaiah 14:12 (NIV)

11 Your pomp is brought down to Sheol, the sound of your harps; maggots are the bed beneath you, and worms are your covering.
12“How you are fallen from heaven, O Day Star, son of Dawn! How you are cut down to the ground, you who laid the nations low!
13 You said in your heart, 'I will ascend to heaven; above the stars of God I will set my throne on high; I will sit on the mount of assembly in the far north;\\Isaiah 14:11-13 (RSV)
