and he will [again] go out to deceive the nations which are [located] throughout the whole world --- Gog and Magog.

Satan will assemble them together for battle, and they will be as numberless as the sand on the seashore.

And the devil who [had] deceived them was thrown into the lake of fire, [burning] with sulphur, where the beast and the false prophet also are. [See 19:20]. And [there] these [enemies of God] will be tortured day and night forever and ever.

Therefore, from one man [Abraham], who was as good as dead [i.e., because of having a sterile wife], were born descendants as numerous as the stars in the sky and as countless as the [grains of] sand on the seashore.
