Isaiah 10:23

For the Lord God of hosts shall make a consumption,.... Not of the land of Judea, as at the destruction of Jerusalem; but the meaning is, that he that is Lord of all, who does what he pleases in the armies above and below, will execute and accomplish a precise and absolute decree of his, concerning the salvation of the remnant of his people; which is his decree of election, and that standing sure, not upon the foot of works, but his own sovereign will: hence their salvation is sure and certain, and not precarious;

even determined, in the midst of all the land; that is, the determined decree should be executed in the several parts of the land of Judea, where this remnant was; for which reason the Gospel was preached in the several cities of Judah, in order to accomplish it, both by Christ and his apostles.
