For I could wish that myself were {a} accursed from Christ for my brethren, my kinsmen according to the {b} flesh:

(a) The apostle loved his brethren so completely that if it had been possible he would have been ready to have redeemed the castaways of the Israelites with the loss of his own soul forever: for this word accursed signifies as much in this place.

(b) Being brethren by flesh, as from one nation and country.

People's New Testament

9:3 For I could wish that myself were accursed from Christ. He could wish this, if that would avail anything, to save his Jewish brethren. In the Revised Version, accursed is rendered by the transliterated Greek word anathema, i.e. rejected from Christ and lost.

My brethren. His Jewish brethren, those of the same Jewish stock as himself.

Wesley's Notes

9:3 I could wish - Human words cannot fully describe the motions of souls that are full of God. As if he had said, I could wish to suffer in their stead; yea, to be an anathema from Christ in their place. In how high a sense he wished this, who can tell, unless himself had been asked and had resolved the question? Certainly he did not then consider himself at all, but only others and the glory of God. The thing could not be; yet the wish was pious and solid; though with a tacit condition, if it were right and possible.

King James Translators' Notes

accursed: or, separated

Jamieson-Fausset-Brown Bible Commentary

3. For I could wish that myself were accursed from Christ for-"in behalf of"

my brethren, my kinsmen according to the flesh-In proportion as he felt himself severed from his nation, he seems to have realized all the more vividly their natural relationship. To explain away the wish here expressed, as too strong for any Christian to utter or conceive, some have rendered the opening words, "I did wish," referring it to his former unenlightened state; a sense of the words too tame to be endured: others unwarrantably soften the sense of the word "accursed." But our version gives the true import of the original; and if it be understood as the language rather of "strong and indistinct emotions than of definite ideas" [Hodge], expressing passionately how he felt his whole being swallowed up in the salvation of his people, the difficulty will vanish, and we shall be reminded of the similar idea so nobly expressed by Moses (Ex 32:32).

Matthew Henry's Concise Commentary

9:1-5 Being about to discuss the rejection of the Jews and the calling of the Gentiles, and to show that the whole agrees with the sovereign electing love of God, the apostle expresses strongly his affection for his people. He solemnly appeals to Christ; and his conscience, enlightened and directed by the Holy Spirit, bore witness to his sincerity. He would submit to be treated as accursed, to be disgraced, crucified; and even for a time be in the deepest horror and distress; if he could rescue his nation from the destruction about to come upon them for their obstinate unbelief. To be insensible to the eternal condition of our fellow-creatures, is contrary both to the love required by the law, and the mercy of the gospel. They had long been professed worshippers of Jehovah. The law, and the national covenant which was grounded thereon, belonged to them. The temple worship was typical of salvation by the Messiah, and the means of communion with God. All the promises concerning Christ and his salvation were given to them. He is not only over all, as Mediator, but he is God blessed for ever.
