A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown [1882]
Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself--These are not the precise words of Exo 20:7; but they express all that it was currently understood to condemn, namely, false swearing (Lev 19:12, &c.). This is plain from what follows. But I say unto you, Swear not at all--That this was meant to condemn swearing of every kind and on every occasion--as the Society of Friends and some other ultra-moralists allege--is not for a moment to be thought. For even Jehovah is said once and again to have sworn by Himself; and our Lord certainly answered upon oath to a question put to Him by the high priest; and the apostle several times, and in the most solemn language, takes God to witness that he spoke and wrote the truth; and it is inconceivable that our Lord should here have quoted the precept about not forswearing ourselves, but performing to the Lord our oaths, only to give a precept of His own directly in the teeth of it. Evidently, it is swearing in common intercourse and on frivolous occasions that is here meant. Frivolous oaths were indeed severely condemned in the teaching of the times. But so narrow was the circle of them that a man might swear, says LIGHTFOOT, a hundred thousand times and yet not be guilty of vain swearing. Hardly anything was regarded as an oath if only the name of God were not in it; just as among ourselves, as TRENCH well remarks, a certain lingering reverence for the name of God leads to cutting off portions of His name, or uttering sounds nearly resembling it, or substituting the name of some heathen deity, in profane exclamations or asseverations. Against all this our Lord now speaks decisively; teaching His audience that every oath carries an appeal to God, whether named or not. neither by heaven; for it is God's throne--(quoting Isa 66:1);

Notes on the Bible, by Albert Barnes, [1834]
Thou shalt not forswear thyself - Christ here proceeds to correct another false interpretation of the law. The law respecting oaths is found in Lev 19:12, and Deu 23:23. By those laws people were forbid to perjure themselves, or to forswear, that is, swear falsely. Perform unto the Lord - Perform literally, really, and religiously what is promised in an oath. Thine oaths - An oath is a solemn affirmation or declaration, made with an appeal to God for the truth of what is affirmed, and imprecating his vengeance, and renouncing his favor if what is affirmed is false. A false oath is called perjury, or, as in this place, forswearing. It appears, however, from this passage, as well as from the ancient writings of the Jewish rabbins, that while the Jews professedly adhered to the law, they had introduced a number of oaths in common conversation, and oaths which they by no means considered to be binding. For example, they would swear by the temple, by the head, by heaven, by the earth. So long as they kept from swearing by the name Yahweh, and so long as they observed the oaths publicly taken, they seemed to consider all others as allowable, and allowedly broken. This is the abuse which Christ wished to correct. "It was the practice of swearing in common conversation, and especially swearing by created things." To do this, he said that they were mistaken in their views of the sacredness of such oaths. They were very closely connected with God; and to trifle with them was a species of trifling with God. Heaven is his throne; the earth his footstool; Jerusalem his special abode; the head was made by him, and was so much under his control that we could not make one hair white or black. To swear by these things, therefore, was to treat irreverently objects created by God, and could not be without guilt. It is remarkable that the sin here condemned by the Saviour prevails still in Palestine in the same form and manner referred to here. Dr. Thomson (The Land and the Book, vol. ii. p. 284) says, "The people now use the very same sort of oaths that are mentioned and condemned by our Lord. They swear by the head, by their life, by heaven, and by the temple, or what is in its place, the church. The forms of cursing and swearing, however, are almost infinite, and fall on the pained ear all day long." 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. See Exo 22:11; Lev 5:1; Num 5:19; Deu 29:12, Deu 29:14.

Perform unto the Lord - Perform literally, really, and religiously what is promised in an oath.

Thine oaths - An oath is a solemn affirmation or declaration, made with an appeal to God for the truth of what is affirmed, and imprecating his vengeance, and renouncing his favor if what is affirmed is false. A false oath is called perjury, or, as in this place, forswearing.

Explanatory Notes on the Whole Bible, by John Wesley [1754-65]
Our Lord here refers to the promise made to the pure in heart of seeing God in all things, and points out a false doctrine of the scribes, which arose from their not thus seeing God. What he forbids is, the swearing at all, by any creature, in our ordinary conversation: both of which the scribes and Pharisees taught to be perfectly innocent. Exo 20:7.

Adam Clarke Commentary on the Whole Bible - Published 1810-1826
Thou shalt not forswear thyself - They dishonor the great God, and break this commandment, who use frequent oaths and imprecations, even in reference to things that are true; and those who make vows and promises, which they either cannot perform, or do not design to fulfill, are not less criminal. Swearing in civil matters is become so frequent, that the dread and obligation of an oath are utterly lost in it. In certain places, where oaths are frequently administered, people have been known to kiss their thumb or pen, instead of the book, thinking thereby to avoid the sin of perjury; but this is a shocking imposition on their own souls. See the notes on Deu 4:26; Deu 6:13. Perform unto the Lord thine oaths - The morality of the Jews on this point was truly execrable: they maintained, that a man might swear with his lips, and annul it in the same moment in his heart. Rab. Akiba is quoted as an example of this kind of swearing. See Schoettgen.
