Mateus 5

43 "You have heard that it was said, 'Thou shalt love thy neighbor and hate thine enemy.'

44 But I say to you, Love your enemies and pray for those who persecute you,

45 that you may be sons of your Father in heaven; for he makes his sun to rise upon the bad and the good, and sends rain upon the just and the unjust.

46 For if you love those who love you, what reward have you? Do not also the tax collectors do the same thing?

47 And if you salute your brothers only, what superiority have you? Do not the Gentiles do the same?

48 You must be perfect as your heavenly Father is perfect.
