King James Version

1 Samuel 25:31

That this shall be no grief unto thee, nor offence of heart unto my lord, either that thou hast shed blood causeless, or that my lord hath avenged himself: but when the LORD shall have dealt well with my lord, then remember thine handmaid.

Proverbs 26:2

As the bird by wandering, as the swallow by flying, so the curse causeless shall not come.

Apostolic Constitutions, Book III 15:1

If, therefore, peace returns upon those that sent it, nay, upon those that before had actually given it, because it did not find persons fit to receive it, much rather will a curse return upon the head of him that unjustly sent it, because he to whom it was sent was not worthy to receive it: for all those who abuse others without a cause curse themselves, as Solomon says: As birds and sparrows fly away, so the curse causeless shall not come upon any one. And again he says: Those that bring reproaches are exceeding foolish. But as the bee, a creature as to its strength feeble, if she stings any one, loses her sting, and becomes a drone; in the same manner you also, whatsoever injustice you do to others, will bring it upon yourselves. He has graven and dug a pit, and he shall fall into the same ditch that he has made. And again: He that digs a pit for his neighbour, shall fall into it. Wherefore he that avoids a curse, let him not curse another; for what you hate should be done to you, do not do to another. Wherefore admonish the widows that are feeble-minded, strengthen those of those who are weak, and praise such of them as walk in holiness. Let them rather bless, and not calumniate. Let them make peace, and not stir up contention.

Apostolic Constitutions, Book VI 23:1

For He did not take away the law of nature, but confirmed it. For He that said in the law, The Lord your God is one Lord; the same says in the Gospel, That they might know You, the only true God. And He that said, You shall love your neighbour as yourself, says in the Gospel, renewing the same precept, A new commandment I give unto you, that you love one another. He who then forbade murder, does now forbid causeless anger. He that forbade adultery, does now forbid all unlawful lust. He that forbade stealing, now pronounces him most happy who supplies those that are in want out of his own labours. He that forbade hatred, now pronounces him blessed that loves his enemies. He that forbade revenge, now commands long-suffering; not as if just revenge were an unrighteous thing, but because long-suffering is more excellent. Nor did He make laws to root out our natural passions, but only to forbid the excess of them. He who had commanded to honour our parents, was Himself subject to them. He who had commanded to keep the Sabbath, by resting thereon for the sake of meditating on the laws, has now commanded us to consider of the law of creation, and of providence every day, and to return thanks to God. He abrogated circumcision when He had Himself fulfilled it. For He it was to whom the inheritance was reserved, who was the expectation of the nations. He who made a law for swearing rightly, and forbade perjury, has now charged us not to swear at all. He has in several ways changed baptism, sacrifice, the priesthood, and the divine service, which was confined to one place: for instead of daily baptisms, He has given only one, which is that into His death. Instead of one tribe, He has appointed that out of every nation the best should be ordained for the priesthood; and that not their bodies should be examined for blemishes, but their religion and their lives. Instead of a bloody sacrifice, He has appointed that reasonable and unbloody mystical one of His body and blood, which is performed to represent the death of the Lord by symbols. Instead of the divine service confined to one place, He has commanded and appointed that He should be glorified from sunrising to sunsetting in every place of His dominion. He did not therefore take away the law from us, but the bonds. For concerning the law Moses says: You shall meditate on the word which I command you, sitting in your house, and rising up, and walking in the way. And David says: His delight is in the law of the Lord, and in His law will he meditate day and night. For everywhere would he have us subject to His laws, but not transgressors of them. For says He: Blessed are the undefiled in the way, who walk in the law of the Lord. Blessed are they that search out His testimonies; with their whole heart shall they seek Him. And again: Blessed are we, O Israel, because those things that are pleasing to God are known to us. And the Lord says: If you know these things, happy are you if you do them.
