Love your neighbors and Hate your enemy?

Matthew 5:43-48 (Complete Jewish Bible)

43"You have heard that our fathers were told, `Love your neighbors -- and hate your enemy.'44But I tell you, love your enemies! Pray for those who persecute you!45Then 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.46What reward do you get if you love only those who love you? Why, even tax-collectors do that!47And if you are friendly only to your friends, are you doing anything out of the ordinary? Even the Goyim do that!48Therefore, be perfect, just as your Father in heaven is perfect.
