13 Then the sixth angel blew his trumpet, and I heard a voice from ^lthe four horns of the golden altar before God, 14 saying to the sixth angel who had the trumpet, “Release ^mthe four angels who are bound at ⁿthe great river Euphrates.” 15 So the four angels, who had been prepared for the hour, the day, the month, and the year, were released ^oto kill a third of mankind.
