Revelation 9:13-15

New Matthew Bible

¹³ And the sixth angel blew. And I heard a voice from the four corners of the golden altar that is before God, ¹⁴ saying to the sixth angel who had the trumpet, Release the four angels that are bound in the great river Euphrates! ¹⁵ And the four angels were released, who were prepared for an hour, for a day, for a month, and for a year, to slay the third part of man-kind.
