Isaiah 10:22
For though thy people Israel be as the sand of the sea, yet a remnant of them shall return: the consumption decreed shall overflow with righteousness.
For though thy people Israel be as the sand of the sea,.... These words are spoken either by the Lord to the prophet, calling Israel his people; or by the prophet to Hezekiah, as Jarchi and Kimchi think; or they may be rendered thus, "for though thy people, O Israel, be as the sand of the sea" {s}; that is, innumerable, as was promised to Abraham, Genesis 22:17:
yet a remnant of them shall return; or "be converted in it" {t}, to the Messiah; or "be saved", as the apostle interprets it,
See Gill on "Romans 9:27"; a remnant is a few, as Kimchi explains it, out of a great number: it signifies, that the majority of the Jewish nation should reject the Messiah, only a few of them should believe in him; and these should certainly believe in him, and be saved by him; and that for the following reason, because
the consumption decreed shall overflow with righteousness; that is, the precise and absolute decree, concerning the salvation of the remnant, God will cause to overflow, or abundantly execute, in a righteous manner, consistent with his divine perfections; and so it makes for the comfort of the remnant of the Lord's people, agreeably to the intent of the apostle's citation of it, See Gill on "Romans 9:28"; though some understand it of God's punitive justice, in consuming and destroying the greater part of the Jewish people, the ungodly among them, and saving a remnant, which return and repent; and to this sense are the Targum, and the Jewish commentators.
