Jesus' Attitude toward Adultery
27 "You have heard that it was said, "You shall not commit adultery.' 28 But I say to you that everyone who looks at a woman with lust has already committed adultery with her in his heart. 29 If your right eye causes you to sin, tear it out and throw it away; it is better for you to lose one of your members than for your whole body to be thrown into hell. 30 And if your right hand causes you to sin, cut it off and throw it away; it is better for you to lose one of your members than for your whole body to go into hell.
Jesus' Attitude toward Divorce
31 "It was also said, "Whoever divorces his wife, let him give her a certificate of divorce.' 32 But I say to you that anyone who divorces his wife, except on the ground of unchastity, causes her to commit adultery; and whoever marries a divorced woman commits adultery.
Jesus' Attitude toward Oaths
33 "Again, you have heard that it was said to those of ancient times, "You shall not swear falsely, but carry out the vows you have made to the Lord.' 34 But I say to you, Do not swear at all, either by heaven, for it is the throne of God, 35 or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. 36 And do not swear by your head, for you cannot make one hair white or black. 37 Let your word be "Yes, Yes' or "No, No'; anything more than this comes from the evil one.
Love for Enemies
38 "You have heard that it was said, "An eye for an eye and a tooth for a tooth.' 39 But I say to you, Do not resist an evildoer. But if anyone strikes you on the right cheek, turn the other also; 40 and if anyone wants to sue you and take your coat, give your cloak as well; 41 and if anyone forces you to go one mile, go also the second mile. 42 Give to everyone who begs from you, and do not refuse anyone who wants to borrow from you.
43 "You have heard that it was said, "You shall love your neighbor and hate your enemy.' 44 But I say to you, Love your enemies and pray for those who persecute you, 45 so that you may be children of your Father in heaven; for he makes his sun rise on the evil and on the good, and sends rain on the righteous and on the unrighteous. 46 For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? 47 And if you greet only your brothers and sisters, what more are you doing than others? Do not even the Gentiles do the same? 48 Be perfect, therefore, as your heavenly Father is perfect.
