This Beast is a fallen angel.

Jude 6-7

6 “And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.”

7 “Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.”

This Beast is the king over the locusts which are released from the bottomless pit in Revelation 9:11.

Revelation 9:11, “And they had a king over them, which is the angel of The Bottomless Pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.”

Study Revelation 9.

This Beast’s name in Greek is Apollyon.

After he is released from the bottomless pit, he rebels against his father, Satan, just as Lucifer, now Satan, rebelled against his Father, the Lord.

Study Isaiah 14:12-16.

Apollyon torments the ones who do not have the seal of God in their foreheads.

Revelation 9:4, “And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.”

He is tormenting the followers of Satan.

This is part of his rebellion against his father, Satan, as he tries to take over his Father’s throne.

This is a duality. Lucifer rebelled against his Father, the Lord, and tried to take over his father's throne.

This Beast is the Son of Perdition (Son of Satan) spoken of in II Thessalonians 2:3-4 who sits himself up as God here on earth.

II Thessalonians 2:3-4

3 “Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness[a] is revealed, the man doomed to destruction.”

4 “He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God.”

This Beast person becomes Pope of the Catholic Church. He receives a deadly wound and is healed.

After he is healed of his deadly wound, he proclaims himself to be God.

II Thessalonians 2:3-4.

Revelation 13:3-10.

The Beast then rules the world for forty-two months.

Revelation 13:5-7

5 “And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.”

6 “And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.”

7 “And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.”

This Beast is the Beast who was, is not, and yet is and shall ascend out of the bottomless pit.

Revelation 17:8, “The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.”

Revelation 17:11, “And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.”

He was (was locked in the bottomless pit), is not (not locked in the bottomless pit), and yet is (can only do what the Lord will permit).

He is the Beast who ascends out of the bottomless pit and kills the two witnesses.

Revelation 11:7, “ And when they shall have finished their testimony, (The two witnesses) the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.”

This Beast is the Beast who along with ten kings destroys the Catholic Church, the wife of Satan.

This is part of his rebellion against his father, Satan.

The Beast of The Bottomless Pit is Apollyon, the Son of Satan.
