And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
*Nations could have been translated as region.
This verse uses the word “all” and specifically the phrase “nations” when speaking of the Antichrist. This verse employs a grammatical construct—an exaggeration of sorts or an emphatic type of statement—in order to convey the writers point. Grammarians call this construct hyperbole. It is a statement like, “Cretans are always liars, vicious brutes, lazy gluttons.” This type of language is actually found quite frequently in Revelation and the Bible.
Another example, “O king, the Most High God gave your father Nebuchadnezzar sovereignty and greatness and glory and splendor. Because of the high position he gave him, all the peoples and nations and men of every language dreaded and feared him. (Daniel 5:18–19) Did every single nation on earth fear Nebuchadnezzar? No! Only the nations that had heard of him, feared him? Was this spoken to every last nation of the earth? No! Only those nations that were in close enough surrounding area to Babylon to be effected. Were the native peoples of the US living in dread of Nebuchadnezzar? No!
“All the peoples and nations and men of every language” is more of an exaggeration.
One more example, Men of all nations came to listen to Solomon’s wisdom, sent by all the kings of the world, who had heard of his wisdom. (I Kings 4:34)
Is this verse another expression of hyperbole is used to deliver the great amount of renown that Solomon had. Yes! Were the writers justified in using such emphatic expressions? Yes! They are used to make a point. We need to understand that not the “whole world” will follow the Anti-Christ, but his influence might be felt.
