Abaddon means "destroyer". In the Book of Revelations, he rules over the creatures that will torment all men without the seal of God upon their head, and he is the one that will bind Satan for a thousand years. He is the angel of death and destruction and of the bottomless pit.
In the Old Testament, the word is used to mean a place of destruction and is associated with sheol, the shadowy Jewish realm of the dead. Milton's Paradise Regained likewise uses the term to describe a place.
As early as the third century, Abaddon was also described as a demon and possibly equated with Satan. Magical texts such as the Greater Key of Solomon also identify Abaddon as demonic.
2. AdramalechAccording to 2 Kings in the Bible, Adramalech was a Samarian god to whom children were sacrificed. He is sometimes compared to other Mesopotamian deities, including Moloch. He is included in demonographical works as an arch-demon.
3. ApollyonThe Book of Revelations specifies that Apollyon is the Greek name for Abaddon. Barrett's The Magus, however, lists both demons as distinct from one another.
4. AsmodeusMeaning "creature of judgment," Asmodeus may have roots in a Zoroastrian demon, but he appears in the Book of Tobit, the Talmud and other Jewish texts. He is associated with lust and gambling.
The Book of Enoch reports that Azazel was a leader of rebellious giants who taught men how to wage war and taught women how to make themselves more attractive. Theistic Satanists commonly associate Azazel with enlightenment and a source of forbidden knowledge.
In the Book of Leviticus, two sacrificial goats are offered to God. The choice one is sacrificed while the other is sent to Azazel as a sin offering. "Azazel" here might refer to a location or a being. Either way, Azazel is connected with wickedness and impurity.
Jewish and Islamic lore both tell of Azazel being an angel that refused to bow down to Adam as per God's command.
6. BaalberithThe Book of Judges uses this term to describe the primary god in an area known as Shechem. The name literally means "God of the Covenant," although covenant here would refer to a political arrangement between the Jews and Shechem, not the covenant between the Jews and God. Some sources link the figure with Beelzebub. He was later listed as a demon in Christian demonology.
7. BalaamThe Biblical and Talmudic Balaam is a non-Israelite prophet who conspires against the Israelites. The Book of Revelations, 2 Peter and Jude associate him with greed and avarice, of which LaVey makes him a devil.
Commonly translated as "Lord of the Flies," he was a local Canaanite deity mentioned in the Old Testament (often as Baal Zebub, with "baal" meaning "lord"). He also gained several New Testament Biblical mentions, where he is described not as a pagan god but specifically as a demon and equated with Satan.
In occult texts, Beelzebub is generally understood to be a very high ranking demon in Hell, and at least one source states that he actually overthrew Satan, who is turn now battles to get back his position.
