Revelation 9:13-15

New International Reader's Version

¹³ The sixth angel blew his trumpet. Then I heard a voice coming from the four corners of the golden altar. The altar stands in front of God. ¹⁴ The voice spoke to the sixth angel who had the trumpet. The voice said, “Set the four angels free who are held at the great river Euphrates.” ¹⁵ The four angels had been ready for this very hour and day and month and year. They were set free to kill a third of all people.
