Revelation 9:11  KJV  "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."

Interpretation based on the study:  Another authority, intent to hold, engross, occupy and control, touching your dominion and ascendency.  Inducing to drive and lead you in shameful, lamentable deprivation, hopeless, pathetic, cruel, vile, hateful and hostile.  Deriving recognition and praise on your account, to meddle and transgress, crossing over to overrun violently, disregarding right, showing no pity, vindictive, unbridled and out of control.  This selfsame messenger of destruction derive benefit and notoriety from death and destruction, exhausting to expend with abandon, corrupting to defile, squander and dissipate in impulsivity and wantonness.  Completely reckless, venomous and malignant, forfeited to succumb in ruin.  And in extreme diabolical defiant wrathful, severe, inhospitable, intractable bitterness and envy, continue to worship evil, for the sake to cause complete, full destruction and death.
