Satan and His "Angels "Isaiah 14:12-15 Ezekiel 28:15-17;

Isaiah 14:12-15 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!

13 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:

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

15 Yet thou shalt be brought down to hell, to the sides of the pit.

Ezekiel 28:15-17Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.

16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.

17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.

Luke 10:18 And he said unto them, I beheld Satan as lightning fall from heaven.

1 Peter 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:

Revelation 12:12Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
