And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea. (Revelation 20:8)
Textual evidence favors (cf. p. 10) the reading “for the battle.” The definite article lays stress on a particular battle, the last conflict between God and those in rebellion against Him. See GC 663-665.
Nations … Gog and Magog.
These terms represent the hosts of the unsaved of all ages who come forth in the second resurrection. For a discussion of the names “Gog” and “Magog” and the application of these symbols in OT prophecy and in the present passage see on Eze. 38:1, 2.
Sand of the sea.
That is, beyond computation (cf. Gen. 22:17). This host is composed of all the unsaved from the foundation of the world.
