“The famous Alexander, too, instigated by his love of disputation in the true fashion of heretical temper, has made himself conspicuous against us; he will have us say that Christ put on flesh of an earthly origin, in order that He might in His own person abolish sinful flesh.”

“"Alexander the coppersmith did me much evil; the Lord reward him according to his works." Here he again makes mention of his trial, not wishing merely to censure and accuse the man, but to prepare his disciple for the conflicts, that he might bear them firmly. Though they be mean and contemptible persons, and without honor, who cause these trials, they ought all, he says, to be borne with fortitude. For he who suffers wrong from any great personage, receives no little distinction from the superiority of him who does the wrong. But he who is injured by a vile and abject person, suffers the greater annoyance. "He did me much evil," he says, that is, he persecuted me in various ways. But these things will not go unpunished! For the Lord will reward him according to his works. As he said above: "What persecutions I endured, but out of them all the Lord delivered me." (2 Tim iii. 11.) So also here he consoles his disciples by a double consideration, that he himself had suffered wrong, and that the other would be rewarded for his evil deeds. Not that the Saints rejoice in the punishment of their persecutors, but that the cause of the Gospel required it, and the weaker would derive consolation from it. "Of whom be thou ware also; for he hath greatly withstood our words." That is, he is hostile to us, and opposes us. He has not said, Revenge, punish, expel him, although by the grace given him he might have so done, but he does no such thing; nor does he arm Timothy against him, but only commands him to avoid him, leaving vengeance to God, and for the consolation of the weaker he has said that He will reward him, which is a prophecy rather than an imprecation.”

“He asks to be visited, and first he calls him to himself; second he indicates his own condition, at "Alexander"; third he concludes the epistolary greeting, at "they greet you." Again, first he commands that he come; second he assigns him a companion, at "take Mark"; third he shows what he should bring, at "the cloak." Concerning the first he does two things, for first he calls him; second he assigns the cause of the calling, at "Demas." He says therefore: because I am soon to depart from the world, hasten to come to me quickly. And this, that they might console one another, and that he might help him in the preaching of the Gospel, for which he was anxious, being in chains. Prov. 18:19: A brother who is helped by a brother is like a strong city. The cause of the calling is that he was deprived of the fellowship due to him. And first by one who had departed on account of his own fault; second, because he had sent certain ones to preach. He says therefore "for Demas," etc., that is, he preferred the love of this age to love of me. 1 John 2:15: If anyone loves the world, the charity of the Father is not in him. Crescens, a certain disciple, went into Galatia, sent by the apostle. Titus also, sent by him, went into Dalmatia, where in the end he is said to have been bishop. Job 38:35: Will you send lightnings, and will they go? "Luke alone is with me" — this one he retained in the preaching of the Gospel, in which he was gracious. 2 Cor. 8:18: whose praise is in the Gospel throughout all the Churches. Then when he says "Take Mark, and bring him," he assigns him a companion; and concerning this he does two things. First he assigns him a companion; second, the reason for this. This Mark is called by another name John, and is the cousin of Barnabas. Acts 15:37f. it is said that Barnabas wanted to take Mark, but Paul was unwilling. And on account of this a dissension arose between them, so that he departed from them. Col., last chapter: Mark, the cousin of Barnabas. The reason is, "because he is useful to me," etc. Then when he says "the cloak," etc., he says what he should carry. Carpus is a certain saint. The "penula" according to Jerome was a scroll of the law, which they had on paper in the manner of a roll, and this he calls the "penula." Or "penula" is said to be some garment; but, according to Chrysostom, it was a common garment. And because the apostle at Rome was poor, not receiving from others, therefore he wanted a garment to be brought to him. Haymo says that it was a special garment as a sign of nobility. Hence in Acts 22:25, Paul said that he was a Roman citizen. For Paul's father served the Romans at Tarsus of Cilicia; and from this he was made a Roman citizen: and the "penula" was a garment as a sign of the consul. And perhaps his father was consul there. Or "penula" is said to be a satchel where the books were, which seems to be the case, because there follows "and the books." But what need had the apostle, full of the Holy Spirit, of books? Again, his dissolution was at hand. I respond. It must be said that it was on account of two things. First, that in reading he might have comfort. 1 Macc. 12:9: having the holy books for comfort. For in books there is a remedy against tribulations. Or he says this lest they be lost, but might remain for the faithful. Again, the more he was approaching death, the more he pressed on with the service of the Scriptures; just as it is said of Ambrose that up to his last illness he did not cease to write; hence, while writing that Ps. 47:2: "Great is the Lord, and greatly to be praised," etc., he died. "But especially the parchments." Parchments are unwritten papers, or leaflets, where he had written his letters, or his sermons. Then when he says "Alexander," etc., he shows what things were with him, and what things are with him. And first on the part of men; second on the part of God, at "but the Lord stood by me." Again the first is divided into two; for first he tells him about a certain one who was against him; second about the negligence of those who did not help him, at "in my first defense," etc. Again, first he sets forth the fault of the one wickedly attacking; second he shows his future punishment, at "the Lord will repay him," etc.; third he shows how he is also to be punished according to the Church, at "whom you also avoid." It seems that this Alexander was a coppersmith, or a keeper of the treasury; and he was one of those who said that the legal observances were to be kept as necessary for salvation. 1 Tim. 1:19: concerning the faith they have made shipwreck, of whom is Hymenaeus and Alexander. And some say that this is the one about whom it is said in Acts 19:24, because he stirred up a sedition against the apostle; but the name disagrees, because that one was Demetrius, this one Alexander, and Luke; because that one was at Ephesus, this one at Rome. And he adds "he showed me many evils." And note that he does not say "he did," but that "he showed," because the wicked can show their intent against the just, but do not always carry it out, Jer. 1:19. Jer. 15:20: They will fight against you, and will not prevail, because I am with you. Job 5:12: who scatters the thoughts of the malicious, so that their hands cannot accomplish what they have begun. Who catches the wise in their own cunning, and scatters the counsel of the wicked. Then when he says "the Lord will repay him," etc., he sets down his future punishment. But note that he does not put the optative verb, "may he repay," but says "he will repay"; because it is signified that the punishment has been prepared by God, which the apostle foresaw from his obstinacy. Ps. 61:13: because you will repay each one according to his works. Yet, together with the fact that punishment is reserved for him in the future, the Church ought also to punish him by excommunicating him. Hence he adds "whom you also avoid," namely as a heretic. Titus 3:10: A heretical man, after one and a second correction, avoid. Of this saying he also gives the reason, saying "for he greatly withstood our words." Acts 7:51: You have always resisted the Holy Spirit. Consequently he sets down the negligence of those not helping him; and first he reproves their fault; second he asks pardon for them, at "may it not be imputed to them." He says therefore "in my first," etc. The Gloss says that the apostle often fought against Alexander who taught wrongly, and in person no one stood by him. But this does not seem to be his meaning here, because this Alexander was not so great that the apostle needed others to dispute with him. But it must be said that, as it is said in Acts 25:21: "Paul, appealing, was sent to Rome," and therefore it was necessary that he be presented to Caesar, that the cause of his mission be examined, and the Jews came against him. And this the apostle calls his first defense. In which the disciples were absent to him, fearing lest they be punished by the cruel Nero. Ecclus. 51:10: I was looking for the help of men, and there was none. Is. 63:3: I have trodden the winepress alone, and of the nations there is no man with me. But it could be said that this was because from the beginning no one knew. But this is false; rather, they withdrew out of a certain faintheartedness. Ps. 87:19: You have put far from me friend and neighbor, and my acquaintances, because of misery. Job 6:15: My brothers have passed by me, etc. But because they did it out of weakness, he prays for them, and does not excommunicate, saying "may it not be imputed to them." Luke 6:28: Pray for those who slander you. Then when he says "but the Lord," he shows what is done concerning him on the part of God, whose help he first sets down; second, the effect of this, at "and let them hear." He says therefore: all have forsaken me, but where man is lacking, God offers himself. Ps. 24: for my father and my mother have forsaken me, but the Lord has taken me up. Hence he says "the Lord stood by me," namely to help me. Jer. 20:11: The Lord is with me like a mighty warrior. Ps. 15:8: I foresaw the Lord always in my sight, because he is at my right hand, that I be not moved. And how? "And he strengthened me," giving fortitude of soul, so that I would not be stunned before Caesar. Ezek. 3:14: the hand of the Lord was with me, strengthening me. And this "that through me," etc., which is fulfilled when it is spread to many, and when what is said by mouth is fulfilled by deed. Acts 9:15: a vessel of election, etc. Then when he says "and let them hear," the effect of the divine help is set down. And first as to the past; second as to the future; third he gives thanks. But the benefit regarding the past is twofold, namely deliverance from fault and from punishment. He says therefore: the Lord stood by me, and therefore in that summons I was delivered, because I was not condemned by Caesar; but it was permitted to me that I might go where I wished. And therefore he says "and let all the nations hear," namely that others might be encouraged along with him to come. Ps. 95:5: Declare his glory among the nations. And that the insult of the Jews might be put down. And he adds "I was delivered from the mouth of the lion," that is, from the cruelty of Nero. Prov. 19:12: As the roaring of lions, so is the wrath of a king. Prov. 28:15: A roaring lion and a hungry bear is a wicked prince over a poor people. Second, he was delivered from fault; hence he says "the Lord delivered me from every evil work." But some are delivered from punishment, falling into the fault of denial of the faith. Ps. 17:18: He rescued me from my most powerful enemies, and from those who hated me, etc. And this through God. Wis. 8:21: I cannot be continent unless God grants it. "In the future he will save me." Is. 45:17: Israel is saved in the Lord with an eternal salvation. And he says "into the heavenly kingdom." Luke 22:29: I dispose to you, as my Father has disposed to me, a kingdom. Matt. 5:12: your reward is abundant in heaven. And therefore he gives thanks, "to whom be glory." 1 Tim. 1:17: to the king of ages. Then when he says "greet," etc., he enjoins on him the greeting of others; second he greets him on the part of others; third on his own part. Again, concerning the first, first he enjoins the greeting of others; second he determines the time of coming. He says therefore "greet Prisca," namely who is the woman, "and Aquila," the husband of Prisca, whom he puts first because perhaps they were more devout, "and the household of Onesiphorus." But why not him, but the household? Because perhaps he was dead, and therefore he greets the family; or perhaps because he was with him at Rome. Determining the time of coming, first he shows the necessity; second he pursues his purpose. The necessity is on account of others remaining in other places. Again, on account of the disturbance of the sea. Then he sets down the persons greeting, as is evident. And in the usual manner, lest the letter be corrupted, he writes in his own hand: "Grace be with you. Amen."”

“At my first answer no man stood with me,.... Meaning, that when he made his first defence against the charges laid unto him in one of the courts of judicature in Rome, no man appeared in his cause, to speak to his character, to be a witness for him, or plead his cause: but all men forsook me; all his friends, all that came with him from Judea, or from Asia; see Ti2 1:15 being timorous of coming into danger, and of the loss of their lives; as the disciples of Christ were, when he was apprehended, who all at that time forsook him and fled: I pray God that it may not be laid to their charge; that this sin may not be imputed to them, or they be punished for it, but that it might be pardoned; so differently does he express himself on the account of these, than on the account of the coppersmith; he sinning through malice, wilfully and obstinately, these through surprise, temptation, and weakness.”

“Alexander the coppersmith - We are not to understand this of any tradesman, but of some rabbin; for it was not unusual for the Jews to apply the name of some trade as an epithet to their rabbins and literary men. He is, in all probability, the very same mentioned Act 19:33 (note); and it is not unlikely that he may have been the same whom the apostle was obliged to excommunicate, Ti1 1:20. The Lord reward him - Αποδῳη αυτῳ ὁ Κυριος· But instead of αποδῳη, which has here the power of a solemn imprecation, αποδωσει, he will reward, is the reading of the very best MSS., several of the versions, and some of the chief Greek fathers. This makes the sentence declaratory: The Lord Will reward him according to his works. This reading is most like the spirit and temper of this heavenly man. See Ti2 4:16.”

“The Lord will render [8] to him. We read shall render, not only in the Latin and Syriac, but also in divers Greek manuscripts which Dr. Wells again prefers before the ordinary Greek copies, in which we read, The Lord render or reward him, as in the Protestant translation. If that was the true reading, we must take the words by way of a prophecy, and not as an imprecation or curse. (Witham)”

“G. P. "the Lord reward," etc. Most critics prefer the Vulgate reading, which is respectably supported by manuscripts, among them, by that used by St. Chrysostom. The charity of the apostle, of which we have evidence in v. 16, does not permit us to regard this as a curse.”

“Alexander the coppersmith--or "smith" in general. Perhaps the same as the Alexander (see on Ti1 1:20) at Ephesus. Excommunicated then he subsequently was restored, and now vented his personal malice because of his excommunication in accusing Paul before the Roman judges, whether of incendiarism or of introducing a new religion. See my Introduction. He may have been the Alexander put forward by the Jews in the tumult at Ephesus (Act 19:33-34). reward--The oldest manuscripts read, "shall reward," or "requite him." Personal revenge certainly did not influence the apostle (Ti2 4:16, end).”
