“Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates.”
King James Version (KJV)
9:14 Loose the four angels - To go every way; to the four quarters. These were evil angels, or they would not have been bound. Why, or how long, they were bound we know not.
Re 9:14 Loose the four angels which are bound in the great river Euphrates. "At the great river" (Revised Version). The four angels represent four agencies which had been restrained and kept from advancing.
