Revelation 9:11-13

New International Version - UK

¹¹ They had as king over them the angel of the Abyss, whose name in Hebrew is Abaddon and in Greek is Apollyon (that is, Destroyer).

¹² The first woe is past; two other woes are yet to come.

¹³ The sixth angel sounded his trumpet, and I heard a voice coming from the four horns of the golden altar that is before God.
