Matthew 7:12

Therefore all things whatsoever ye would that men - This is a most sublime precept, and highly worthy of the grandeur and beneficence of the just God who gave it. The general meaning of it is this: "Guided by justice and mercy, do unto all men as you would have them to do to you, were your circumstances and theirs reversed." Yet this saying may be misunderstood. "If the prisoner should ask the judge, 'whether he would be content to be hanged, were he in his case,' he would answer, 'No.' Then, says the prisoner, do as you would be done to. - Neither of them must do as private men; but the judge must do by him as they have publicly agreed: that is, both judge and prisoner have consented to a law, that if either of them steal he shall be hanged." - Selden. None but he whose heart is filled with love to God and all mankind can keep this precept, either in its spirit or letter. Self-love will feel itself sadly cramped when brought within the limits of this precept; but God hath spoken it: it is the spirit and design of the law and the prophets; the sum of all that is laid down in the Sacred Writings, relative to men's conduct toward each other. It seems as if God had written it upon the hearts of all men, for sayings of this kind may be found among all nations, Jewish, Christian, and Heathen. See many examples in Wetstein's notes.

All things whatsoever ... - This command has been usually called the "Saviour's golden rule," a name given to it on account of its great value. All that you "expect" or "desire" of others in similar circumstances, do to them. Act not from selfishness or injustice, but put yourself in the place of the other, and ask what you would expect of him. This would make you impartial, candid, and just. It would destroy avarice, envy, treachery, unkindness, slander, theft, adultery, and murder. It has been well said that this law is what the balance-wheel is to machinery. It would prevent all irregularity of movement in the moral world, as that does in a steam-engine. It is easily applied, its justice is seen by all people, and all must acknowledge its force and value.

This is the law and the prophets - That is, this is the sum or substance of the Old Testament. It is nowhere found in so many words, but if is a summary expression of all that the law required. The sentiment was in use among the Jews. Hillel, an ancient Rabbi, said to a man who wished to become a proselyte, and who asked him to teach him the whole law, "Whatever is hateful to you, do not do to another." Something of the same sentiment was found among the ancient Greeks and Romans, and is found in the writings of Confucius.
