And he said unto me, The Lord, before whom I walk, will send his angel with thee, and prosper thy way; and thou shalt take a wife for my son of my kindred, and of my father's house: Then shalt thou be clear from this my oath, when thou comest to my kindred; and if they give not thee one , thou shalt be clear from my oath. And I came this day unto the well, and said, O Lord God of my master Abraham, if now thou do prosper my way which I go:
And Moses spake unto the heads of the tribes concerning the children of Israel, saying, This is the thing which the Lord hath commanded. If a man vow a vow unto the Lord, or swear an oath to bind his soul with a bond; he shall not break his word, he shall do according to all that proceedeth out of his mouth. If a woman also vow a vow unto the Lord, and bind herself by a bond, being in her father's house in her youth; ... But if her husband hath utterly made them void on the day he heard them; then whatsoever proceeded out of her lips concerning her vows, or concerning the bond of her soul, shall not stand: her husband hath made them void; and the Lord shall forgive her. Every vow, and every binding oath to afflict the soul, her husband may establish it, or her husband may make it void. But if her husband altogether hold his peace at her from day to day; then he establisheth all her vows, or all her bonds, which are upon her: he confirmeth them, because he held his peace at her in the day that he heard them .
And it shall be, that whosoever shall go out of the doors of thy house into the street, his blood shall be upon his head, and we will be guiltless: and whosoever shall be with thee in the house, his blood shall be on our head, if any hand be upon him. And if thou utter this our business, then we will be quit of thine oath which thou hast made us to swear. And she said, According unto your words, so be it. And she sent them away, and they departed: and she bound the scarlet line in the window.
For a dream cometh through the multitude of business; and a fool's voice is known by multitude of words. When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed. Better is it that thou shouldest not vow, than that thou shouldest vow and not pay. Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thine hands?
These are the things that ye shall do; Speak ye every man the truth to his neighbour; execute the judgment of truth and peace in your gates: And let none of you imagine evil in your hearts against his neighbour; and love no false oath: for all these are things that I hate, saith the Lord. And the word of the Lord of hosts came unto me, saying,
Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths: But I say unto you, Swear not at all; neither by heaven; for it is God's throne: Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King.
But when Herod's birthday was kept, the daughter of Herodias danced before them, and pleased Herod. Whereupon he promised with an oath to give her whatsoever she would ask. And she, being before instructed of her mother, said, Give me here John Baptist's head in a charger.
And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein. And he that shall swear by heaven, sweareth by the throne of God, and by him that sitteth thereon. Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
And so, after he had patiently endured, he obtained the promise. For men verily swear by the greater: and an oath for confirmation is to them an end of all strife. Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath: That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:
For the law made nothing perfect, but the bringing in of a better hope did ; by the which we draw nigh unto God. And inasmuch as not without an oath he was made priest : (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)
Clement of Alexandria
2nd Century
The man of proved character in such piety is far from being apt to lie and to swear. For an oath is a decisive affirmation, with the taking of the divine name. For how can he, that is once faithful, show himself unfaithful, so as to require an oath; and so that his life may not be a sure and decisive oath?
But he does not even swear, preferring to make averment, in affirmation by "yea," and in denial by "nay." For it is an oath to swear, or to produce anything from the mind in the way of confirmation in the shape of an oath. It suffices, then, with him, to add to an affirmation or denial the expression "I say truly," for confirmation to those who do not perceive the certainty of his answer.
The Gnostic swears truly, but is not apt to swear, having rarely recourse to an oath, just as we have said. And his speaking truth on oath arises from his accord with the truth. This speaking truth on oath, then, is found to be the result of correctness in duties. Where, then, is the necessity for an oath to him who lives in accordance with the extreme of truth? He, then, that does not even swear will be far from perjuring himself.
Irenaeus
2nd Century
For they do not receive from the Father the knowledge of the Son; neither do they learn who the Father is from the Son, who teaches clearly and without parables Him who truly is God. He says: "Swear not at all; neither by heaven, for it is God's throne; nor by the earth, for it is His footstool; neither by Jerusalem, for it is the city of the great King." For these words are evidently spoken with reference to the Creator, as also Esaias says: "Heaven is my throne, the earth is my footstool."
Justin Martyr
2nd Century
And with regard to our not swearing at all, and always speaking the truth, He enjoined as follows: "Swear not at all; but let your yea be yea, and your nay, nay; for whatsoever is more than these cometh of evil." And that we ought to worship God alone, He thus persuaded us: "The greatest commandment is, Thou shalt worship the Lord thy God, and Him only shall thou serve, with all thy heart, and with all thy strength, the Lord God that made thee."
Tertullian
2nd Century
However, it is a defect of custom to say, "By Hercules, So help me the god of faith;" while to the custom is added the ignorance of some, who are ignorant that it is an oath by Hercules. Further, what will an oath be, in the name of gods whom you have forsworn, but a collusion of faith with idolatry? For who does not honour them in whose name he swears?
For when he swore by that which he knew, he really committed no perjury. But it was not a vain oath for him to swear that there was no other God. It would indeed be a vain oath, if there had been no persons who believed that there were other Gods, like the worshippers of idols then, and the heretics of the present day.
We respect in the emperors the ordinance of God, who has set them over the nations. We know that there is that in them which God has willed; and to what God has willed we desire all safety, and we count an oath by it a great oath. But as for demons, that is, your genii, we have been in the habit of exorcising them, not of swearing by them, and thereby conferring on them divine honour.
Arnobius

Cyprian

Gregory Thaumaturgus

This, too, is proper to fools, that they are unreliable. But be thou true to thy word, knowing that it is much better for thee not to vow or promise to do anything, than to vow and then fail of performance. And thou oughtest by all means to avoid the flood of base words, seeing that God will hear them.
Hippolytus
3rd Century
And especially they abstain from wrath and anger, and all such passions, inasmuch as they consider these to be treacherous to man. And no one amongst them is in the habit of swearing; but whatever any one says, this is regarded more binding than an oath. If, however, one will swear, he is condemned as one unworthy of credence.
First, that he will worship the Divinity; next, that he will observe just dealings with men, and that he will in no way injure any one, and that he will not hate a person who injures him, or is hostile to him, but pray for them. He likewise swears that he will always aid the just, and keep faith with all, especially those who are rulers. For, they argue, a position of authority does not happen to any one without God.
Constitutions of the Holy Apostles
4th Century
"Thou shalt not forswear thyself; for it is said, "Thou shalt not swear at all." But if that cannot be avoided, thou shalt swear truly; for "every one that swears by Him shall be commended." "Thou shalt not bear false witness;" for "he that falsely accuses the needy provokes to anger Him that made him."
