Matthew 5:37

"But what," it may be said, "if any one should require an oath, and apply constraint?" Let the fear of God be more powerful than the constraint: since, if thou art to bring forward such excuses, thou wilt keep none of the things which are enjoined. Yea, for first with respect to thy wife thou wilt say, "what if she be contentious and extravagant;" and then as to the right eye, "what if I love it, and am quite on fire?" and of the unchaste look, "what then, if I cannot help seeing?" and of our anger against a brother, "what if I be hasty, and not able to govern my tongue?" and in general, all His sayings thou mayest on this wise trample under foot. Yet surely with regard to human laws thou darest not in any case use this allegation, nor say, "what then if this or that be the case," but, willing or unwilling, thou receivest what is written. And besides, thou wilt never have compulsion to undergo at all. For he that hath hearkened unto those former blessings, and hath framed himself to be such as Christ enjoined, will have no such constraint to endure from any, being held in reverence and veneration by all. "But let your yea, be yea; and your nay, nay: for that which exceedeth these cometh of the evil one." What is it then that "exceeds yea" and "nay"? it is the oath, not the perjury. For this latter is quite acknowledged, and no man needs to learn that it is of the evil one; and it is not an excess, but an opposite: whereas an excess means something more, and added over and above: which kind of thing swearing is. "What then," saith one, "was it of the evil one? and if it was of the evil one, how was it a law?" Well, this same thing thou wilt say concerning the wife also; how is that now accounted adultery, which was before permitted? What now may one reply to this? […]

(ubi sup.) And he who has learned that an oath is to be reckoned not among things good, but among things necessary, will restrain himself as much as he may, not to use an oath without necessity, unless he sees men loth to believe what it is for their good they should believe, without the confirmation of an oath. This then is good and to be desired, that our conversation be only, yea, yea; nay, nay; for what is more than this cometh of evil. That is, if you are compelled to swear, you know that it is by the necessity of their weakness to whom you would persuade any thing; which weakness is surely an evil. What is more than this is thus evil; not that you do evil in this just use of an oath to persuade another to something beneficial for him; but it is an evil in him whose weakness thus obliges you to use an oath.

Otherwise; They who live in the simplicity of the faith have not need to swear, with them ever, what is is, what is not is not; by this their life and their conversation are ever preserved in truth.

Having forbidden swearing, He instructs us how we ought to speak, Let your speech be yea, yea; nay, nay. That is, to affirm any thing it is sufficient to say, 'It is so:' to deny, to say, 'It is not so.' Or, yea, yea; nay, nay, are therefore twice repeated, that what you affirm with the mouth you should prove in deed, and what you deny in word, you should not establish by your conduct.

But let your speech be, Yea, yea; Nay, nay. Lest you ask, "How then will people believe what I say?" He says, "They will believe you if you always tell the truth and never swear at all." For no one is disbelieved more than he …

But let your communication be yea, yea,.... That is, let your speech, in your common conversation, and daily business of life, when ye answer to anything in the affirmative, be "yea"; and when ye answer to anything in the negative, "nay": and for the stronger asseveration of the matter, when it is necessary, double these words; but let no oaths be joined unto them: this is enough; a righteous man's yea, is yea, and his no, is no; his word is sufficient.

But let your communication - Your word; what you say. Be, Yea - Yes. This does not mean that we should always use the word “yea,” for it might as well have been translated “yes”; but it means that we should simply affirm or declare that a thing is so. More than these - More than these affirmations. Cometh of evil - Is evil. Proceeds from some evil disposition or purpose. And from this we may learn: 1. That profane swearing is always the evidence of a depraved heart.

2Co 1:17, 18). for whatsoever is more than these cometh of evil--not "of the evil one"; though an equally correct rendering of the words, and one which some expositors prefer. It is true that all evil in our world is originally of the devil, that it forms a kingdom at the head of which he sits, and that, in every manifestation of it he has an active part.

These verses deserve the closest attention of all readers of the Bible. A right understanding of the doctrines they contain lies at the very root of Christianity. The Lord Jesus here explains more fully the meaning of his words, “I came not to destroy the law but to fulfil.”

These verses deserve the closest attention of all readers of the Bible. A right understanding of the doctrines they contain lies at the very root of Christianity. The Lord Jesus here explains more fully the meaning of his words, “I came not to destroy the law but to fulfil.”He teaches us that his Gospel magnifies the Law, and exalts its authority: he shows us that the Law, as expounded by him, was a far more spiritual and heart-searching rule than most of the Jews supposed; and he proves this by selecting three commandments out of the ten as examples of what he means. He expounds the sixth commandment. Many thought that they kept this part of God’s law so long as they did not commit actual murder. The Lord Jesus shows that its requirements go much further than this. It condemns all angry and passionate language, and especially when used without a cause. Let us mark this well. We may be perfectly innocent of taking life, and yet be guilty of breaking the sixth commandment! He expounds the seventh commandment. Many supposed that they kept this part of God’s law if they did not actually commit adultery. The Lord Jesus teaches that we may break it in our thoughts, hearts and imaginations, even when our outward conduct is moral and correct. The God with whom we have to do looks far beyond actions. With him even a glance of the eye may be a sin! He expounds the third commandment. Many fancied that they kept this part of God’s law so long as they did not swear falsely, and performed their oaths. The Lord Jesus forbids all vain and light swearing altogether. All swearing by created things, even when God’s name is not brought forward—all calling upon God to witness, excepting on the most solemn occasions—is a great sin. Now all this is very instructive. It ought to raise very serious reflections in our minds: it calls us loudly to use great searching of heart.

Let your communication be, Yea, yea; Nay, nay - That is, a positive affirmation, or negation, according to your knowledge of the matter concerning which you are called to testify. Do not equivocate; mean what you assert, and adhere to your assertion. Hear what a heathen says on this subject: - Εχθρος γαρ μοι κεινος ὁμως αιδαο πυλησιν, Ος χ’ετερον μεν κευθει ενι φρεσιν, αλλο δε βαζει. Hom. Il. ix. 312 “He whose words agree not with his private thoughts is as detestable to me as the gates of hell.” See on Joshua 2 (note) at the end. See the subject of swearing particularly considered in the note at the conclusion of Deuteronomy 6 (note). Whatsoever is more than these - That is, more than a bare affirmation or negation, according to the requirements of Eternal Truth, cometh of evil; or, is of the wicked one - εκ του πονηρου εϚιν, i.e. the devil, the father of superfluities and lies. One of Selden’s MSS. and Gregory Nyssen, a commentator of the fourth century, have εκ του διαβολου εϚιν, is of the devil. That the Jews were notoriously guilty of common swearing, for which our Lord particularly reprehends them, and warns his disciples against, and that they swore by heaven, by earth, by Jerusalem, by their head, etc., the following extracts, made by Dr. Lightfoot from their own writings, amply testify: - “It was customary and usual among them to swear by the creatures. ‘If any swear by heaven, by earth, by the sun, etc., although the mind of the swearer be, under these words, to swear by Him who created them, yet this is not an oath. Or, if any swear by some of the prophets, or by some of the books of the Scripture, although the sense of the swearer be to swear by Him that sent that prophet, or that gave that book, nevertheless, this is not an oath. Maimonides.’ “If any adjure another by heaven or earth, he is not guilty. […]
