Revelation 9:13

They have tails like those of scorpions, with stingers. In their tails they have power to harm men for five months.

They have over them as king the angel of the abyss. His name in Hebrew is “Abaddon”, but in Greek, he has the name “Apollyon”.

The first woe is past. Behold, there are still two woes coming after this.

saying to the sixth angel who had the trumpet, “Free the four angels who are bound at the great river Euphrates!”

The four angels were freed who had been prepared for that hour and day and month and year, so that they might kill one third of mankind.

The number of the armies of the horsemen was two hundred million. I heard the number of them.
