Matthew 5:27

But he had withal said above: "Are we, then, making void the law through faith? Far be it; but we are establishing the law " -forsooth in those (points) which, being even now interdicted by the New Testament, are prohibited by an even more emphatic precept: instead of, "Thou shalt not commit adultery," "Whoever shall have seen with a view to concupiscence, hath already committed adultery in his own heart; " and instead of, "Thou shalt not kill," "Whoever shall have said to his brother, Racha, shall be in danger of hell.

Having now finished the former commandment, and having extended it unto the height of self-denial, He, advancing in course and order, proceeds accordingly unto the second, herein too obeying the law. For beginning from those passions, which most belong to our whole race, anger, I mean, and desire (for it is these chiefly that bear absolute sway within us, and are more natural than the rest); He with great authority, even such as became a legislator, both corrected them, and reduced them to order with all strictness. For He said not that the adulterer merely is punished; but what He had done with respect to the murderer, this He doth here also, punishing even the unchaste look: to teach thee wherein lies what He had more than the scribes. Accordingly, He saith, "He that looketh upon a woman to lust after her hath already committed adultery with her:" that is, he who makes it his business to be curious about bright forms, and to hunt for elegant features, and to feast his soul with the sight, and to fasten his eyes on fair countenances. For He came to set free from all evil deeds not the body only, but the soul too before the body. Thus, because in the heart we receive the grace of the Spirit, He cleanses it out first. "And how," one may say, "is it possible to be freed from desire?" I answer, first, if we were willing, even this might be deadened, and remain inactive. In the next place, He doth not here take away desire absolutely, but that desire which springs up in men from sight. […]

Gerontius of Petra said, 'Many people who are tempted by pleasures of the flesh do not sin with the body but lust with the mind; they keep their bodily virginity but lust in their heart. It is better then, beloved, to do what is written, …

(Mor. xxi. 2.) But whoso casts his eyes about without caution will often be taken with the pleasure of sin, and ensnared by desires begins to wish for what he would not. Great is the strength of the flesh to draw us downwards, and the charm of beauty once admitted to the heart through the eye, is hardly banished by endeavour. We must therefore take heed at the first, we ought not to look upon what it is unlawful to desire. For that the heart may be kept pure in thought, the eyes, as being on the watch to hurry us to sin, should be averted from wanton looks.

Ye have heard that it was said, Thou shalt not commit adultery. But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. That is, if one stands gazing and examining, kindling …

Ye have heard that it was said,.... These forms of speech, as well as what follows, by them of old time, have been explained, in ver.

Ye have heard that it was said by them of old time, Thou shalt not commit adultery - See the notes at Mat 5:21. Our Saviour in these verses explains the seventh commandment. It is probable that the Pharisees had explained this commandment, as they had the sixth, as extending only to the external act; and that they regarded evil thoughts and a wanton imagination as of little consequence, or as not forbidden by the law.

Ye have heard that it was said--The words "by," or "to them of old time," in this verse are insufficiently supported, and probably were not in the original text.

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.

Ye have heard that it was said by them of old - By the ancients, τοις αρχαιοις, is omitted by nearly a hundred MSS., and some of them of the very greatest antiquity and authority; also by the Coptic, Ethiopic, Armenian, Gothic, and Sclavonian versions; by four copies of the old Itala; and by Origen, Cyril, Theophylact, Euthymius, and Hilary. On this authority Wetstein and Griesbach have left it out of the text.
