Ye have heard that it was said by them of old time, Thou shalt not commit adultery:

You have heard that it was said to them of old: Thou shalt not commit adultery.

Ye have heard that it has been said, Thou shalt not commit adultery.

'Ye heard that it was said to the ancients: Thou shalt not commit adultery;

You have knowledge that it was said, You may not have connection with another man's wife:

Thou shalt not commit adultery. Christ proceeds with his subject, and shows, that the law of God not only has authority over the life, in a political view, to form the outward manners, but that it requires pure and holy affections of the heart. We must remember what I have already stated, that though Christ quotes the very words of the law, it is the gross and false meaning, which had been put upon it by dishonest interpreters, that he blames. He has already told us, that he did not come as a new Legislator, but as the faithful expounder of a law which had been already given. It might be objected that, through long practice, that interpretation had grown old. Christ expressly admits this, but meets it by saying, that the antiquity of an error ought not to be allowed to plead in its favor.

Ye have heard that it was said by them of old time, Thou shalt not commit adultery - See the notes at Matthew 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. Our Saviour assures them that the commandment did not regard the external act merely, but the secrets of the heart, and the movements of the eye. He declares that they who indulge a wanton desire, that they who look on a woman to increase their lust, have already, in the sight of God, violated the commandment, and committed adultery in the heart. Such was the guilt of David, whose deep and awful crime fully shows the danger of indulging in evil desires, and in the rovings of a wanton eye. See 2 Sam. 11; Ps. 51. See also 2-Peter 2:14. So exceeding strict and broad is the law of God! And so heinous in his sight axe thoughts and feelings which may be forever concealed from the world!

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.

(7) Ye have heard that it was said by them of old time, Thou shalt not commit adultery:
(7) He is taken for an adulterer before God, whoever he is, that covets a woman: and therefore we must keep our eyes chaste, and all the members we have, yea and we must avoid all opportunities that might move us to evil, no matter what it costs us.

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. 21. The law here mentioned,
thou shalt not commit adultery, is recorded in Exodus 20:14 and the meaning of our Lord is, not that the then present Jews had heard that such a law had been delivered "to the ancients", their fathers, at Mount Sinai; for that they could read in their Bibles: but they had received it by tradition, that the sense of it, which had been given to their ancestors, by the ancient doctors of the church, was, that this law is to be taken strictly, as it lies, and only regards the sin of uncleanness in married persons; or, what was strictly adultery, and that actual; so that it had no respect to fornication, or unchaste thoughts, words, or actions, but that single act only.

Victory over the desires of the heart, must be attended with painful exertions. But it must be done. Every thing is bestowed to save us from our sins, not in them. All our senses and powers must be kept from those things which lead to transgression. Those who lead others into temptation to sin, by dress or in other ways, or leave them in it, or expose them to it, make themselves guilty of their sin, and will be accountable for it. If painful operations are submitted to, that our lives may be saved, what ought our minds to shrink from, when the salvation of our souls is concerned? There is tender mercy under all the Divine requirements, and the grace and consolations of the Spirit will enable us to attend to them.

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.
Thou shall not commit adultery--Interpreting this seventh, as they did the sixth commandment, the traditional perverters of the law restricted the breach of it to acts of criminal intercourse between, or with, married persons exclusively. Our Lord now dissipates such delusions.

Thou shalt not commit adultery. The Jewish rabbins held that a man was guiltless who did not commit the act. Christ, as he always did, lays the laws upon the heart. If it is impure, full of unholy desires, one is guilty. It is our duty to keep the heart pure.

Thou shalt not commit adultery - And this, as well as the sixth commandment, the scribes and Pharisees interpreted barely of the outward act. Exodus 20:14.
