Revelation 9:13-15

International Standard Version

The Vision of the Sixth Trumpet

¹³ When the sixth angel blew his trumpet, I heard a voice from the four^[a] horns of the gold altar in front of God. ¹⁴ It told the sixth angel who had the trumpet, “Release the four angels who are held at the great Euphrates River.” ¹⁵ So the four angels who were ready for that hour, day, month, and year were released to kill one-third of humanity.
