43 "You have heard that it was said, 'You shall love your neighbor, and you shall hate your enemy.'
44 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 mistreat you and persecute you,
45 so that you may prove to be sons of your Father in heaven; because He makes His sun rise on the evil and on the good, and He 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 friends only, what more are you doing [than others]? Do not even the tax collectors do so?
48 You therefore be perfect, just as your Father in heaven is perfect.
