Revelation 9:10-12

Darby Translation

¹⁰ and they have tails like scorpions, and stings; and their power [was] in their tails to hurt men five months.

¹¹ They have a king over them, the angel of the abyss: his name in Hebrew, Abaddon, and in Greek he has [for] name Apollyon.

¹² The first woe has passed. Behold, there come yet two woes after these things.
