Revelation 16:12-14

12  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.

13  And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.

14  For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.

When the sixth vial is poured out on the river Euphrates all the armies of the world are gathered together by the satanic trinity (Dragon, Beast, False Prophet) to the staging ground of Megiddo in Israel (Armageddon). The Euphrates River that separates East from West will be dried up so that the armies of the east can walk to Israel. When all the armies of the world are gathered to the valley of decision, they will be judged in the winepress of God. During the next few months, the following scripture will be completely fulfilled.

Joel 3:9   Proclaim  ye this among the Gentiles; Prepare war, wake up the mighty men, let all the men of war draw near; let them come up:

10  Beat your plowshares into swords, and your pruninghooks into spears: let the weak say, I am strong.

11  Assemble yourselves, and come, all ye heathen, and gather yourselves together round about: thither cause thy mighty ones to come down, O LORD.

12  Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about.

13  Put ye in the sickle, for the harvest is ripe: come, get you down; for the press is full, the fats overflow; for their wickedness is great.

14  Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision.

15  The sun and the moon shall be darkened, and the stars shall withdraw their shining.

16  The LORD also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the LORD will be the hope of his people, and the strength of the children of Israel.

17  So shall ye know that I am the LORD your God dwelling in Zion, my holy mountain: then shall Jerusalem be holy, and there shall no strangers pass through her any more.

Satanic angels will use lying signs and wonders to deceive and to gather all those who wish to fight against the God of heaven. They will reap the consequences of such a foolish and futile attempt to war against the real Creator.
