Revelation 9:14

"And the sixth angel poured out his vial upon the great river Euphrates; and the water thereof was dried up, that the way of the kings of the east might be prepared."

"And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men."

"And the name of the third river is Hiddekel: that is it which goeth toward the east of Assyria. And the fourth river is Euphrates. toward...: or, eastward to Assyria"

"David smote also Hadadezer, the son of Rehob, king of Zobah, as he went to recover his border at the river Euphrates."

"And it shall be, when thou hast made an end of reading this book, that thou shalt bind a stone to it, and cast it into the midst of Euphrates:"

"And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree."

"And the seven angels which had the seven trumpets prepared themselves to sound."

"And I saw the seven angels which stood before God; and to them were given seven trumpets."
