Esaias crieth concerning Israel
The apostle having produced proper testimonies in proof of the calling of the Gentiles, proceeds to mention others; showing, that some few of the Jews also were to be called, according to prophecy, founded upon divine predestination; which, though they are full proofs of the calling of some from among the Jews, yet at the same time suggest the casting off of the far greater number of them; and which is the apostle's view in citing them, as appears from what he says both here and in the two following chapters. The first testimony is taken out of ( Isaiah 10:22 Isaiah 10:23 ) , and is prefaced or introduced with these words; which either express the great concern of mind and sorrow of heart, with which the prophet spoke them, even with strong crying and tears, seeing a remnant of them only was to be saved; or they show his heart's desire and prayer to God, "for Israel", as the words may be rendered, how that he cried to the Lord for them, entreated him with earnestness and importunity, and wrestled with him on their behalf; or they declare the presence of mind, the freedom of expression, the boldness and intrepidity with which he delivered this message to the Jews, which he knew must be ungrateful to them; in doing which, he run the risk of losing his interest in their affections, if not his life; and inasmuch very probably they did not choose to hear it, but turned away from him, he cried aloud, he spared not, he lift up his voice like a trumpet, as he is bid to do elsewhere, resolving they should hear what he had to say, from the Lord of hosts. This is a form of speech used by the Jews, in citing Scripture; thus, (xwu) (aybnh) , "the prophet cries" F16, namely, in ( Isaiah 26:1-21 ) , which is spoken of the same prophet as here; and again F17 the Holy Spirit (txwu) , "cries, and says", in some certain passage of Scripture; and in another place F18 the Holy Spirit "cried", saying, as in ( Joel 3:3 ) : "they have cast lots for my people".
Though the number of the children of Israel be as the sand of the sea:
this part of the testimony seems rather to be taken from ( Hosea 1:10 ) , which may easily be accounted for; since the apostle had just cited the words in Hosea, and so carrying them in his mind, transcribes this sentence from thence; it perfectly agreeing in sense with the passage in Isaiah he had in view, where it stands thus, "though thy people Israel be as the sand of the sea", ( Isaiah 10:22 ) ; that is, though the number of them be such as to be compared thereunto; though they are many as the sand of the sea, as the Targum, Kimchi, and Aben Ezra explain it. This was promised unto Abraham, and had its accomplishment in the days of Solomon, and in after times; they were for quantity, for number, as the sand of the sea, even innumerable; and for quality, being barren and unfruitful, a people laden with iniquity, a seed of evildoers:
a remnant shall be saved;
that is, a few persons only; (rav arqy) (jemh) , "few are called a remnant", as Kimchi on the place observes; these are the remnant among the Jews, according to the election of grace; the few that were chosen, though many were called by the external ministry of Christ and his apostles; the little city, and few men in it, even the escaped of Israel, he that was left in Zion, and that remained in Jerusalem; the little flock among them, which were as sheep among wolves; the few that entered in at the strait gate, and found the way to eternal life; the few that shall be saved; and these shall certainly be saved, with a spiritual and eternal salvation. These, according to the prophecy, were to return to the mighty God, the Lord Jesus Christ, the promised Messiah; be converted to him, and so saved by him with an everlasting salvation: God had resolved upon it, whose counsel shall stand; he had promised it in covenant, which is ordered in all things and sure; he sent his Son to save these his people from their sins, who is become the author of eternal salvation to them; the grace of God is efficacious and powerful enough, to make them willing to be saved by Christ, and to bring them to him, to venture upon him, and commit their souls to him, to be saved by him; and almighty power is concerned, to keep them through faith unto salvation: so that this little remnant, through the Father's everlasting and unchangeable love, the Son's purchase, prayers, and preparations, and the spirits grace, which works them up for this selfsame thing, shall be certainly and completely saved; though with respect to the difficulties attending it, which could have been surmounted by none but Christ, and by reason of their discouragements arising from sin, temptations, and persecutions, they may be said to be scarcely saved.
