9. Anticipating the objections which the Jews might raise as to why God permitted their captivity, and when He did restore them, why He did so by a foreign prince, Cyrus, not a Jew (Isa 40:27, &c.), but mainly and ultimately, the objections about to be raised by the Jews against God's sovereign act in adopting the whole Gentile world as His spiritual Israel (Isa 45:8, referring to this catholic diffusion of the Gospel), as if it were an infringement of their nation's privileges; so Paul expressly quotes it (Ro 9:4-8, 11-21).

     6. Refuting the Jews' reliance on their external privileges as God's elect people, as if God could never cast them off. But if the potter, a mere creature, has power to throw away a marred vessel and raise up other clay from the ground, a fortiori God, the Creator, can cast away the people who prove unfaithful to His election and can raise others in their stead (compare Isa 45:9; 64:8; Ro 9:20, 21). It is curious that the potter's field should have been the purchase made with the price of Judas' treachery (Mt 27:9, 10: a potter's vessel dashed to pieces, compare Ps 2:8, 9; Re 2:27), because of its failing to answer the maker's design, being the very image to depict God's sovereign power to give reprobates to destruction, not by caprice, but in the exercise of His righteous judgment. Matthew quotes Zechariah's words (Zec 11:12, 13) as Jeremiah's because the latter (Jer 18:1-19:15) was the source from which the former derived his summary in Zec 11:12, 13 [HENGSTENBERG].

     20, 21. Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made—"didst thou make"

     21. Hath not the potter power over the clay; of the same lump to make one vessel unto honour, and another to dishonour?—"The objection is founded on ignorance or misapprehension of the relation between God and His sinful creatures; supposing that He is under obligation to extend His grace to all, whereas He is under obligation to none. All are sinners, and have forfeited every claim to His mercy; it is therefore perfectly competent to God to spare one and not another, to make one vessel to honor and another to dishonor. But it is to be borne in mind that Paul does not here speak of God's right over His creatures as creatures, but as sinful creatures: as he himself clearly intimates in the next verses. It is the cavil of a sinful creature against his Creator that he is answering, and be does so by showing that God is under no obligation to give His grace to any, but is as sovereign as in fashioning the clay" [HODGE]. But, Second: "There is nothing unjust in such sovereignty."
