“You have heard that it was said, ‘Eye for eye, and tooth for tooth.’ But I say to you, do not show opposition against an evil person; but whoever slaps you on your right cheek, turn the other toward him also. And if anyone wants to sue you and take your tunic, let him have your cloak also. Whoever forces you to go one mile, go with him two. Give to him who asks of you, and do not turn away from him who wants to borrow from you. You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, love your enemies and pray for those who persecute you, so that you may prove yourselves to be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. For if you love those who love you, what reward do you have? Even the tax collectors, do they not do the same? And if you greet only your brothers and sisters, what more are you doing than others? Even the Gentiles, do they not do the same? Therefore you shall be perfect, as your heavenly Father is perfect.
Take care not to practice your righteousness in the sight of people, to be noticed by them; otherwise you have no reward with your Father who is in heaven. So when you give to the poor, do not sound a trumpet before you, as the hypocrites do in the synagogues and on the streets, so that they will be praised by people. Truly I say to you, they have their reward in full. But when you give to the poor, do not let your left hand know what your right hand is doing, so that your charitable giving will be in secret; and your Father who sees what is done in secret will reward you.”
Matthew 5:38-48
