Matthew 5:27-48 New King James Version (NKJV)
Adultery in the Heart
27 “You have heard that it was said [a]to those of old, ‘You shall not commit adultery.’ 28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. 29 If your right eye causes you to [b]sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. 30 And if your right hand causes you to [c]sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
Marriage Is Sacred and Binding
31 “Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ 32 But I say to you that whoever divorces his wife for any reason except [d]sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.
Jesus Forbids Oaths
33 “Again you have heard that it was said to those of [e]old, ‘You shall not swear falsely, but shall perform your oaths to the Lord.’ 34 But I say to you, do not swear at all: neither by heaven, for it is God’s throne; 35 nor by the earth, for it is His footstool; nor by Jerusalem, for it is the city of the great King. 36 Nor shall you swear by your head, because you cannot make one hair white or black. 37 But let [f]your ‘Yes’ be ‘Yes,’ and your ‘No,’ ‘No.’ For whatever is more than these is from the evil one.
Go the Second Mile
38 “You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ 39 But I tell you not to resist an evil person. But whoever slaps you on your right cheek, turn the other to him also. 40 If anyone wants to sue you and take away your tunic, let him have your cloak also. 41 And whoever compels you to go one mile, go with him two. 42 Give to him who asks you, and from him who wants to borrow from you do not turn away.
Love Your Enemies
43 “You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ 44 [g]But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you, 45 that you may be sons of your Father in heaven; for He makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust. 46 For if you love those who love you, what reward have you? Do not even the tax collectors do the same? 47 And if you greet your [h]brethren only, what do you do more than others? Do not even the [i]tax collectors do so? 48 Therefore you shall be perfect, just as your Father in heaven is perfect.
