The short answer

In Leviticus 24 the man who blasphemed the name of the Lord is to be put to death, and Calvin says this shows the object of the Third Commandment was that God's holy name be honored. Barnes says to curse denotes properly to devote to destruction, and in a larger sense to abuse by reproachful words or to express oneself in a violent, profane, and outrageous manner; he reads Psalm 10:7 as profaneness and imprecation and Romans 3:14 as reproachful and opprobrious language. Wesley reads Matthew 12:36 as holding people to account for blasphemous and profane words and for every idle word. Calvin, Barnes, Henry, and Spurgeon say Peter added cursing and swearing to his denial of Christ. Calvin and Barnes on James 3:9 say the same tongue should not bless God and curse men made in his image, and Spurgeon says a Christian cursing is a very awkward spectacle.

The blasphemer of Leviticus 24

7 passages · 4 writers · 1500s to 1800s

Calvin, Henry, Wesley, and Jamieson comment on the man who blasphemed the name of the Lord in Leviticus 24. Henry says a great stress is laid on this law as in no case to be dispensed with, and Wesley says the congregation acts to beget greater dread and abhorrence of blasphemy. Calvin says it is a frivolous subterfuge to require that blasphemies be pardoned because they were uttered in anger.

1563 · John Calvin, Commentaries on the Four Last Books of Moses Arranged in the Form of a Harmony, part 4 Lev.24.10

To proceed, he is said to have “gone out,” not outside the camp, but in public, so that he might be convicted by witnesses; for he would not have been brought to trial if his crime had been secretly committed within the walls of his own house. This circumstance is also worthy of remark, that, although the blasphemy had escaped him in a quarrel, punishment was still inflicted upon him; and assuredly it is a frivolous subterfuge to require that blasphemies should be pardoned on the ground that they have been uttered in anger; for nothing is more intolerable than that our wrath should vent itself upon God, when we are angry with one of our fellow-creatures. Still it is usual, when a person is accused of blasphemy, to lay the blame on the ebullition of passion, as if God were to endure the penalty whenever we are provoked. The verb נקב, nakab, which some render to express, is here rather used for to curse, or to transfix; and the metaphor is an appropriate one, that God’s name should be said to be transfixed, when it is insultingly abused.

1706–1708 · Matthew Henry, Commentary on Leviticus 24.10-23

A great stress is laid upon this law, as in no case to be dispensed with: He shall surely be put to death; they shall certainly stone him. Those that lightly esteemed God's honour might think it hard to make a man an offender for a word (words are but wind); but God would let them know that they must not make light of such words as these, which come from malice against God in the heart of him that speaks, and must occasion either great guilt or great grief to those that hear. 2. It is made to extend to the strangers that sojourned among them, as well as those that were born in the land. God never made any law to compel strangers to be circumcised and embrace the Jewish religion (proselytes made by force would be no honour to the God of Israel), but he made a law to restrain strangers from speaking evil of the God of Israel. 3. He that was put to death for blasphemy is said to bear his sin, in the punishment of it; no sacrifice being appointed, on the head of which the sin might be transferred, he himself was to bear it upon his own head, as a sacrifice to divine justice. So his own tongue fell upon him (Ps. lxiv. 8), and the tongue of a blasphemer will fall heavily.

Texts on cursing, swearing, and profane words

9 passages · 7 writers · 1500s to 1800s

Barnes says to curse denotes properly to devote to destruction, and that in Psalm 10:7 and Romans 3:14 it covers profane, imprecating, and reproachful speech. Calvin says the Hebrew word in Jeremiah 44:12 sometimes means a curse though it properly signifies an oath, because men in swearing often introduce a curse. Henry says in Proverbs 26:2 that passion makes men scatter causeless curses, and Edwards says cursing is spoken of as a very dreadful sin in the Old Testament.

1754 · John Wesley, Explanatory Notes on Matthew 12.36

Ye may perhaps think, God does not so much regard your words. But I say to you - That not for blasphemous and profane words only, but for every idle word which men shall speak - For want of seriousness or caution; for every discourse which is not conducive to the glory of God, they shall give account in the day of judgment.

1834 · Albert Barnes, Notes on the Bible: Romans 12.14

To curse denotes properly to devote to destruction. Where there is power to do it, it implies the destruction of the object. Thus, the fig-tree that was cursed by the Saviour soon withered away: Mar 11:21. Thus, those whom God curses will be certainly destroyed; Mat 25:41. Where there is not power to do it, to curse implies the invoking of the aid of God to devote to destruction. Hence, it means to imprecate; to implore a curse from God to rest on others; to pray that God would destroy them. In a larger sense still, it means to abuse by reproachful words; to calumniate; or to express oneself in a violent, profane, and outrageous manner.

Bible examples: Peter, Shimei, and Job

10 passages · 7 writers · 1500s to 1900s

Calvin, Henry, Barnes, Robertson, Brown, and Spurgeon comment on Peter's cursing and swearing when he denied Christ. Henry says David hoped the Lord would requite him good for Shimei's cursing, and says the word translated curse in Job 1 is the one that ordinarily signifies to bless. Barnes notes that Dr. Good contends the Hebrew word in Job 1:5 should always be rendered bless.

1555 · John Calvin, Commentary on a Harmony of the Evangelists Matthew, Mark, and Luke, part 3 Matt.26.74

In this third denial, Peter’s unfaithfulness to his Master reached its utmost height. Not satisfied with swearing, he breaks out into cursing, by which he abandons his body and soul to destruction; for he prays that the curse of God may fall upon him, if he knows Christ. It is as much as if he had said, May I perish miserably, if I have any thing in common with the salvation of God!

1708 · Matthew Henry, Commentary on 2 Samuel 16.5-14

He comforts himself with hopes that God would, in some way or other, bring good to him out of his affliction, would balance the trouble itself, and recompense his patience under it: "The Lord will requite me good for his cursing. If God bid Shimei grieve me, it is that he himself may the more sensibly comfort me; surely he has mercy in store for me, which he is preparing me for by this trial." We may depend upon God as our pay-master, not only for our services, but for our sufferings. Let them curse, but bless thou.

1901 · Charles Haddon Spurgeon, Spurgeon's Sermons, Volume 47 (1901) 2735

You never need believe a man who swears—you may know that he also lies. But Peter, having the common notion that to blaspheme and to use strong language would be convincing, began to curse and to swear. Do not alter these words, so as to make it appear that Peter used gentle and polite expressions. He did nothing of the kind—he used the strongest form of cursing that he could, for the Greek word is tantamount to "anathema." He anathematized himself, invoked upon himself the heaviest curses—as profane people usually do—in order that those who stood around might believe him when he said that he did not know Christ. This cursing and swearing shows how very low Peter had fallen. When a man swears, you may, as a rule, be quite sure that he does not know Christ. Peter may have thought within himself, "There never was a disciple of Christ yet who took to swearing, so, if I swear, they will think at any rate that I am not one." So he borrows, out of the mouth of the profane language which did not belong to him—and he utters it in order that they may really think that he is no disciple of Christ. When the cock crew, and he thought of all this, he might well weep.

James 3:9-10 and Romans 12:14: blessing and cursing from one mouth

16 passages · 14 writers · 1st c. to 1900s

Calvin and Barnes say it is a hypocrisy or an absurdity for the same tongue to bless God and curse men made in his image. Fausset says the mouth that emits cursing cannot really emit blessing, and Spurgeon says blessing and cursing must not proceed from the same mouth. Evans, Spurgeon, and Edwards cite the rule "Bless, and curse not."

c. 150–200 · Anonymous (Testaments of the Twelve Patriarchs), The Testaments of the Twelve Patriarchs 12.6

The good mind hath not two tongues, of blessing and of cursing, of insult and of honour, of sorrow and of joy, of quietness and of trouble, of hypocrisy and of truth, of poverty and of wealth; but it hath one disposition, pure and uncorrupt, concerning all men.

c. 1550–1551 · John Calvin, Commentary on James 3.9

9 Therewith, or, by it, bless we God. It is a clear instance of its deadly poison, that it can thus through a monstrous levity transform itself; for when it pretends to bless God, it immediately curses him in his own image, even by cursing men. For since God ought to be blessed in all his works, he ought to be so especially as to men, in whom his image and glory peculiarly shine forth. It is then a hypocrisy not to be borne, when man employs the same tongue in blessing God and in cursing men.

1834 · Albert Barnes, Notes on the Bible: James 3.9

The apostle does not mean that the same man does this, but that all this is done by the same organ - the tongue. Even the Father - Who sustains to us the relation of a father. The point in the remark of the apostle is, the absurdity of employing the tongue in such contradictory uses as to bless one who has to us the relation of a father, and to curse any being, especially those who are made in his image. The word bless here is used in the sense of praise, thank, worship. And therewith curse we men - That is, it is done by the same organ by which God is praised and honored. Which are made after the similitude of God - After his image, Gen 1:26-27. As we bless God, we ought with the same organ to bless those who are like him. There is an absurdity in cursing men who are thus made, like what there would be in both blessing and cursing the Creator himself.

1692 · Thomas Watson, The Ten Commandments 2.3

When we use God’s name in idle discourse. He is not to be spoken of but with a holy awe upon our hearts. To bring his name in at every turn, when we are not thinking of him, to say, ‘O God!’ or, ‘O Christ!’ or, ‘As God shall save my soul’ — is to take God’s name in vain. How many are guilty here! Though they have God in their mouths, they have the devil in their hearts.

1906 · Charles Haddon Spurgeon, Spurgeon's Sermons, Volume 52 (1906) 2996

Never use them, I pray you, as hasty, thoughtless expressions. God's name must never be taken in vain. I fear that there are some who do this and are not rebuked for it. When we say, "O God," there ought to be something solemn to follow.

No filthy speech. He first forbids believers to use any filthy language, including under this name all those expressions which are wont to be employed for the purpose of inflaming lust. Not satisfied with the removal of the vice, he enjoins them to frame their discourse for edification.

1890 · Charles Haddon Spurgeon, Spurgeon's Sermons, Volume 36 (1890) 2124

Surely some men, who can scarcely speak without swearing, have the devil in them! How one's blood runs chill, in going down our streets, to hear how commonly our working men degrade themselves with filthy conversation! It is not exactly cursing—it is less honest and more vile!

1571 · Church of England, The Thirty-Nine Articles of Religion 39

As we confess that vain and rash Swearing is forbidden Christian men by our Lord Jesus Christ, and James his Apostle, so we judge, that Christian Religion doth not prohibit, but that a man may swear when the Magistrate requireth, in a cause of faith and charity, so it be done according to the Prophet’s teaching, in justice, judgement, and truth.

1647 · Westminster Assembly, The Westminster Confession of Faith 22.2

The name of God only is that by which men ought to swear, and therein it is to be used with all holy fear and reverence. Therefore, to swear vainly, or rashly, by that glorious and dreadful Name; or, to swear at all by any other thing, is sinful, and to be abhorred. Yet, as in matters of weight and moment, an oath is warranted by the Word of God, under the new testament as well as under the old; so a lawful oath, being imposed by lawful authority, in such matters, ought to be taken.

1834 · Albert Barnes, Notes on the Bible: Matthew 5.33

Our Saviour here evidently had no reference to judicial oaths, or oaths taken in a court of justice. It was merely the foolish and wicked habit of swearing in private conversation; of swearing on every occasion and by everything that he condemned. This he does condemn in a most unqualified manner. He himself, however, did not refuse to take an oath in a court of law, Mat 26:63-64. So Paul often called God to witness his sincerity, which is all that is meant by an oath. See Rom 1:9; Rom 9:1; Gal 1:20; Heb 6:16. Oaths were, moreover, prescribed in the law of Moses, and Christ did not come to repeal those laws.

1907 · Charles Haddon Spurgeon, Spurgeon's Sermons, Volume 53 (1907) 3031

No, no: for whatever is more than these comes of evil. If words mean anything, this command of Christ is an utter abolishment of oaths taken before magistrates as well as everywhere else. I can make nothing else out of it—indeed, it must mean that because Christ contrasts His teaching with that of former ages—"It has been said by them of old time, You shall not forswear yourself, but shall perform unto the Lord your oaths: but I say unto you, Swear not at all." A man who cannot be believed upon his word, certainly cannot be believed upon his oath and, usually, when a man tells a lie, the next thing he does is swear to it.

386–429 · Augustine of Hippo, Letters 47.2

Nevertheless it is, beyond all doubt, worse to swear falsely by the true God than to swear truly by the false gods; for the greater the holiness of that by which we swear, the greater is the sin of perjury.

1265–1273 · Thomas Aquinas, Summa Theologica II-II, q. 98, a. 2, co.

I answer that, As stated above (Q[89], A[1]), to swear is to call God as witness. Now it is an irreverence to God to call Him to witness to a falsehood, because by so doing one implies either that God ignores the truth or that He is willing to bear witness to a falsehood. Therefore perjury is manifestly a sin opposed to religion, to which it belongs to show reverence to God.
