Revelation 9:13-15

21st Century King James Version

¹³ And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which stands before God,

¹⁴ saying to the sixth angel who had the trumpet, “Loose the four angels who are bound in the great river Euphrates.”

¹⁵ And the four angels were loosed, who had been prepared for an hour and a day and a month and a year, to slay a third part of men.
