And Isaiah cries out concerning Israel, "[Even] if the number of the sons of Israel is like the sand of the sea, the remnant will be saved,

And therefore these were fathered from one man, and [he] being as good as dead, as the stars of heaven in number and like the innumerable sand by the shore of the sea.

And he stood on the sand of the sea.

and he will go out to deceive the nations [that are] at the four corners of the earth, Gog and Magog, to assemble them for battle, {whose number} [is] like the sand of the sea.
