(1) I say the truth in Christ.—The meaning of this expression seems to be, “From the bottom of my soul, in the most sacred part of my being, as a Christian man united to Christ, I make this solemn asseveration.”
My conscience.—Here, as in Romans 2:15, very much in the modern sense of the word, the introspective faculty which sits in judgment upon actions, and assigns to them their moral qualities of praise or blame. “This conscience of mine being also overshadowed with the Holy Spirit, and therefore incapable of falsehood or self-deception.”

(3) I could wish . . .—Rather, I could have wished. The wish, of course, related to what was really impossible. Still it is a nobly generous impulse, at which some weak minds have been shocked, and out of which others have made sentimental capital. Let us leave it as it is.
Accursed from Christ.—Separated from Christ, and devoted to destruction. Does not the intensity of this expression help us to realise one aspect of the Atonement—“being made a curse for us” (Galatians 3:13)? (The Greek word for “curse” is different, but comes to be nearly equivalent.)

(4) The adoption.—They are the theocratic people, the people whom God had, as it were, adopted to Himself, and taken into the special filial relation. (Comp. Hosea 11:1, “I called my son out of Egypt;” Exodus 4:22, “Israel is my son, even my firstborn;” et al.)
The glory.—The Shechinah, or visible symbol of God’s presence. (Comp. Exodus 16:10; Exodus 24:16; Exodus 40:34-35; 1 Samuel 4:22; 1 Kings 8:10-11; Ezekiel 1:28; Hebrews 9:5.)
The covenants.—Not the two tables of stone, but the several compacts made by God with Abraham and his descendants (Genesis 12:1-3; Genesis 12:7; Genesis 13:14-17; Genesis 15:1-21; Genesis 17:1-22; Genesis 22:15-18; Genesis 26:2-5; Genesis 26:34; Genesis 28:13-15; Genesis 35:9-12; Genesis 46:3-4).
The service of God.—The temple service and ritual.
The promises.—Especially the Messianic promises, a term correlative to the “covenants” above.

(5) The fathers.—The patriarchs—Abraham, Isaac, and Jacob.
Who is over all, God blessed for ever.—These words are a well-known subject for controversy. Trinitarian and English interpreters, as a rule, take them with the punctuation of the Authorised version, as referring to Christ. Socinian interpreters, with some of the most eminent among the Germans, put a full stop after “came,” and make the remainder of the verse a doxology addressed to God, “Blessed for ever be God, who is over all.” Both ways are possible. The question is, Which is the most natural and probable? and this is to be considered, putting altogether on one side prepossessions of every kind. We are not to read meaning into Scripture, but to elicit meaning from it. The balance of the argument stands thus:—(1) The order of the words is somewhat in favour of the application to Christ. If the clause had really been a formal doxology, the ascription of blessing would more naturally have come at the beginning in Greek as in English, “Blessed be God,” &c. (2) The context is also somewhat in favour of this application. The break in the form of the sentence becomes rather abrupt on the other hypothesis, and is not to be quite paralleled. Intruded doxologies, caused by a sudden access of pious feeling, are not uncommon in the writings of St. Paul, but they are either worked into the regular order of the sentence, as in Romans 1:25, Galatians 1:5, or else they are formally introduced as in 2 Corinthians 11:31; 1 Timothy 1:17. (3) But on the other hand, to set somewhat decidedly against this application, is the fact that the words used by the Apostle, “Who is over all,” and the ascription of blessing in all other places where they occur, are referred, not to Christ, but to God. (Comp. Romans 1:25; 2 Corinthians 1:3; 2 Corinthians 11:31; Ephesians 1:3; Ephesians 4:6.) There is, indeed, a doxology addressed to Christ in 2 Timothy 4:18; it should, however, be remembered that the Pauline origin of that Epistle has been doubted by some, though it is also right to add that these doubts do not appear to have any real validity. The title “God” does not appear to be elsewhere applied to our Lord by St. Paul, though all the attributes of Godhead are ascribed to Him: e.g., in Philippians 2:6 et seq., Colossians 1:15 et seq. In 1 Timothy 3:16, which would be an apparent exception, the true reading is, * Who was manifested,” and not “God was manifested.” On the other hand, St. John certainly makes use of this title, not only in John 1:1; John 20:28, but also in the reading, adopted by many, of John 1:18, “God only begotten” for “Only begotten Son.” Weighing the whole of the arguments against each other, the data do not seem to be sufficient to warrant a positive and dogmatic conclusion either way. The application to our Lord appears perhaps a little the more probable of the two. More than this cannot be said. Nor is a stronger affirmation warranted by any considerations resting on the division of authorities.

(6) Not as though.—The scholar will observe that there appears to be here a mixture of two constructions, “the case is not such that,” and “I do not mean to say that,” “I do not intend to say that the case is such as that.”
Taken none effect.—“Fallen through,” or “failed of its accomplishment.”
Of Israel—i.e., descended from Jacob. (Comp. Genesis 32:28.) The promise of God was indeed given to Israel, but that did not mean roundly all who could claim descent from Jacob without further limitation.

(7) Neither are all the bodily descendants of Abraham also his spiritual descendants. It was expressly stated from the first that the promise was confined to a particular branch of his posterity. The posterity of Abraham, strictly so called, was to be that derived through Isaac. This is very nearly the sense of the original, “In Isaac shall thy seed be called,” i.e., in “Isaac shalt thou have posterity, which shall be called thy posterity”—“true and legitimate descendants,” thus excluding the seed of Hagar.

(8) They which are the children.—The Apostle explains this restriction in a spiritual sense. Mere natural descent gives no claim to membership in the theocracy.
Of the promise—i.e., not merely “promised children,” but “children born through the miraculous agency of the promise;” the promise is regarded as being possessed of creative power. (Comp. Romans 4:18-20.)

(9) This is the word of promise.—Rather, this saying is of promise. The children of promise, I say, for the saying, “At this time will I come,” &c., is a matter of promise; it implied a divine and miraculous intervention, and did not come in the ordinary course of nature.
At this time—i.e., at the corresponding time of the next year.

(12) The elder shall serve the younger.—The margin gives as an alternative rendering, “the greater shall serve the lesser.” The quotation is taken from the LXX., in which there is the same ambiguity.
This ambiguity also appears to exist in the Hebrew, where it is a disputed question whether the words refer to age or to the comparative strength of the two peoples. In either case, it is the nations that should spring from Esau and Jacob that are meant.

(14) Is there unrighteousness?—Again, as in Romans 3:5, the Apostle anticipates a possible objection. Does not this apparently arbitrary choice of one and rejection of another imply injustice in Him who exercises it? The thought is not to be entertained.

(15) For he saith to Moses.—In the most characteristic period of the Old Testament the divine favour was promised in this way to Moses and denied to Pharaoh. The original of the first quotation has reference to the special revelation vouchsafed to Moses on Sinai, “I will show grace to whom I will show grace.”

(16) Of him that runneth.—A metaphor taken from the foot-races as St. Paul may very possibly have seen them practised at Corinth. (Comp. Romans 9:16; Galatians 2:2; Galatians 5:7; Philippians 2:16.) The meaning is that the prize does not depend on human will or human effort, but on the grace of God.

(17) The converse proposition is also true, that God also uses the wickedness of men as a means of exhibiting His power and justice.
Raised thee up.—Brought into the world and on to the scene of history.
Show my power.—By the plagues of Egypt and by the overthrow of Pharaoh and his host in the Red Sea.

(18) Summary conclusion from the above.
He hardeneth.—The doctrine of the divine sovereignty is here expressed in its most trenchant and logical form. In Exodus 8:32; Exodus 9:34; Exodus 13:15, &c., the hardening of Pharaoh’s heart is attributed to his own act. That act may, however, be regarded as a part of the design of Providence. God’s decrees include human free-will, without destroying it. But how they do this we cannot say.

(20) Nay but, O man.—The answer is not so much a solution of the intellectual difficulty, as an appeal to the religious sense to prevent it from being raised. That His dealings should be questioned at all is a breach of the reverence due to God.

(21) Hath not the potter . . .?—In strict logic, this verse would supply a confirmation, rather than a refutation, of the original objection. If man is merely as clay in the hands of the potter, it would not be un-reasonable to say, “Why doth He yet find fault?” No one would think of blaming a piece of earthenware because it was well or badly made. The argument of the Apostle is not directed to this. He has left the point with which he started in Romans 9:19, and is engaged in proving the position taken up in Romans 9:20. Whatever they may be, God’s dealings are not to be canvassed by men. Still, we cannot overlook the fact that there is apparently a flaw in the logic, though, perhaps, only such a flaw as is inseparable from our necessarily imperfect conceptions of this mysterious subject. The two lines of thought—that which proves the divine sovereignty and that which proves human freedom—run parallel to each other, and are apt to collude when drawn together. (See Notes on Romans 8:29-30; Romans 9:11; Romans 9:18, above.)
For the imagery of the clay and the potter, compare Isaiah 64:8; Jeremiah 18:3-10.

(22) What if . . .—The sentence in the original is incomplete. In its full form it would run, “If God willing to show His wrath” . . . (what can man reply?) This latter clause is dropped or lost in the course of the argument. The best and simplest expedient to supply its place is that adopted in the Authorised version, inserting “what” in italics at the beginning: “What if,” &c. There is a second suppression later in the sentence. At the end of Romans 9:23 we should have to insert some such clause as “He reserved His glory for them,” in order to make the sentence strictly grammatical. These irregularities are due to the Apostle’s habit of dictating, and to the lively flow of his thoughts.
Willing.—While His will was (ultimately) to execute His wrath and display His sovereign judicial power, nevertheless He bore with evildoers, and gave them time for repentance.

(24) Even us.—So far the form of the sentence had been abstract—“vessels of wrath,” “vessels of glory.” Now the Apostle explains who are meant by these abstract terms. The “vessels of glory” are those who were intended to accept the Christian teaching, whether Jews or Gentiles. The “vessels of wrath” are the unbelieving mass of the people of Israel.

(25) As he saith also in Osee.—The original of the prophecy in Hosea relates to the pardon and reconciliation promised to the apostate and idolatrous people of the northern kingdom. It is here typically and prophetically applied to the Gentiles. Those who had ceased to belong to the chosen people, and those who had never belonged to it, were to all intents and purposes in the same position.
Osee.—“It may be questioned whether this word should be pronounced as a dissyllable, the double e being regarded as an English termination, as in Zebedee, Pharisee, &c., or as a tri-syllable, the word being considered as a reproduction of the Greek form of the name.” (Lightfoot, On Revision, p. 156, n.)

(26) And it shall come to pass.—This, too, was originally spoken of the restoration of the northern exiles to the land of Palestine. As applied to the conversion of the Gentiles, it would mean that the lands which had previously been heathen should become Christian. There is some doubt whether the Hebrew of Hosea should not rather be translated, “instead of calling them,” for “in her place where it was said unto them.” Instead of calling them “Ye are not my people,” they will be called “Sons of the living God.” So Ewald and Hitzig.

(27) Crieth.—With reference to the impassioned utterance of the prophet.
A remnant.—Rather, the remnant, with an emphasis upon the word. “The remnant, and only the remnant.”
Shall be saved.—In the original, shall return—i.e., as it is explained in the previous verse, “return to God.” St. Paul has followed the LXX. in putting the consequences of such conversion for the conversion itself.

(28) For he will finish.—Literally, according to the correct reading, For a sentence, accomplishing and abridging it, will the Lord execute upon the earth; in other words, “A short and summary sentence will the Lord execute upon the earth.” The severity of the sentence is a proof that only a remnant can be saved from it. St. Paul follows the LXX., with but slight deviation. The sense of the Hebrew appears to be somewhat different:—“For though thy people. O Israel, were as the sand of the sea, but a remnant of them shall return: a destruction is decreed overflowing with righteousness—i.e., penal justice. For destruction by a sure decree will Jehovah of Hosts perform in the midst of all the earth.” (Cheyne.)

(29) Said before—i.e., in an earlier part of his book. The Book of Isaiah was at this time collected in the form in which we have it. In Acts 13:33, we find an express reference to the present numbering of the Psalms—“It is also written in the second psalm, Thou art my Son, this day have I begotten thee.” (Some authorities read “first,” the two psalms being arranged as one, but “second” is probably the true reading.)
A seed.—Equivalent to the “remnant” of Romans 9:27. The point of the quotation is, that but for this remnant the rejection of Israel would have been utter and complete.

(30) Which followed not after righteousness.—Not having a special revelation, and being inattentive to the law of conscience.
Attained to righteousness.—By accepting the offer of Christianity, and especially the Christian doctrine of justification by faith.

(31) Israel, on the other hand, though ostensibly pursuing a law the object of which was righteousness, did not reach such a law. They tried to keep the Law, but failed to keep it, and to bring themselves under its protection. The second “righteousness” is omitted in the best MSS.

(32) For they stumbled.—“For,” in this clause, should be omitted, and the two clauses thrown together, the words “of the law” also going out—Because (seeking righteousness), not of faith, but as if of works, they stumbled, &c.
That stumblingstone.—Christ. When Christianity, with the justification by faith which goes with it, was offered to them, they “were offended,” and refused it.

(33) Behold, I lay in Sion.—A free combination of Isaiah 28:16—“Behold, I lay in Zion for a foundation a stone; . . . he that believeth shall not make haste”—and Isaiah 8:14, “And He shall be . . . for a stone of stumbling and for a rock of offence to both the houses of Israel.” In the first of these passages the prophet refers to the foundation-stone of the Temple as a symbol of the divine faithfulness; in the second to God Himself. St. Paul, like the Jewish Rabbis, applied both passages to the Messiah; not wrongly, for they foretold the triumph of the theocracy which was fulfilled in the Messiah. The same two quotations appear in 1 Peter 2:6-7, and with similar variation from the LXX., but they are there kept distinct.
Shall not be ashamed.—So, too, the LXX. The Hebrew is, “Shall not make haste.”
