Apocalipse 9

13 And at the sounding of the sixth angel a voice came to my ears from the horns of the gold altar which is before God,

14 Saying to the sixth angel who had the horn, Make free the four angels who are chained at the great river Euphrates.

15 And the four angels were made free, who were ready for the hour and day and month and year, that they might put to death a third part of men.
