Matthew 5:33-37; Matthew 5:43-48

33 "Again, you have heard that our fathers were told, `Do not break your oath,' and `Keep your vows to ADONAI.'

34 But I tell you not to swear at all -- not `by heaven,' because it is God's throne;

35 not `by the earth,' because it is his footstool;p and not `by Yerushalayim,' because it is the city of the Great King.

36 And don't swear by your head, because you can't make a single hair white or black.

37 Just let your `Yes' be a simple `Yes,' and your `No' a simple `No'; anything more than this has its origin in evil.

43 "You have heard that our fathers were told, `Love your neighbors -- and hate your enemy.'

44 But I tell you, love your enemies! Pray for those who persecute you!

45 Then you will become children of your Father in heaven. For he makes his sun shine on good and bad people alike, and he sends rain to the righteous and the unrighteous alike.

46 What reward do you get if you love only those who love you? Why, even tax-collectors do that!

47 And if you are friendly only to your friends, are you doing anything out of the ordinary? Even the Goyim do that!

48 Therefore, be perfect, just as your Father in heaven is perfect.
