Revelation 9:12-14

Darby Translation

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

¹³ And the sixth angel sounded [his] trumpet: and I heard a voice from the four horns of the golden altar which [is] before God,

¹⁴ saying to the sixth angel that had the trumpet, Loose the four angels which are bound at the great river Euphrates.
