Revelation 16:13-16 New King James Version (NKJV)
13 And I saw three unclean spirits like frogs coming out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet. 14 For they are spirits of demons, performing signs, which go out to the kings [a]of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
15 “Behold, I am coming as a thief. Blessed is he who watches, and keeps his garments, lest he walk naked and they see his shame.”
16 And they gathered them together to the place called in Hebrew, [b]Armageddon.
Revelation 16:13-16 New International Version (NIV)
13 Then I saw three impure spirits that looked like frogs; they came out of the mouth of the dragon, out of the mouth of the beast and out of the mouth of the false prophet. 14 They are demonic spirits that perform signs, and they go out to the kings of the whole world, to gather them for the battle on the great day of God Almighty.
15 “Look, I come like a thief! Blessed is the one who stays awake and remains clothed, so as not to go naked and be shamefully exposed.”
16 Then they gathered the kings together to the place that in Hebrew is called Armageddon.
