Hebrew Bible

Leviticus 19:17

15 “‘You must not deal unjustly in judgment: You must neither show partiality to the poor nor honor the rich. You must judge your fellow citizen fairly. 16 You must not go about as a slanderer among your people. You must not stand idly by when your neighbor’s life is at stake. I am the Lord. 17 You must not hate your brother in your heart. You must surely reprove your fellow citizen so that you do not incur sin on account of him. 18 You must not take vengeance or bear a grudge against any of your people, but you must love your neighbor as yourself. I am the Lord. 19 You must keep my statutes. You must not allow two different kinds of your animals to breed together, you must not sow your field with two different kinds of seed, and you must not wear a garment made of two different kinds of material. 20 “‘When a man goes to bed with a woman for intercourse, although she is a slave woman designated for another man and she has not yet been ransomed, or freedom has not been granted to her, there will be an obligation to pay compensation. They must not be put to death, because she was not free.

New Testament

Matthew 18:15

14 In the same way, your Father in heaven is not willing that one of these little ones be lost. 15If your brother sins, go and show him his fault when the two of you are alone. If he listens to you, you have regained your brother. 16 But if he does not listen, take one or two others with you, so that at the testimony of two or three witnesses every matter may be established. 17 If he refuses to listen to them, tell it to the church. If he refuses to listen to the church, treat him like a Gentile or a tax collector. 18 “I tell you the truth, whatever you bind on earth will have been bound in heaven, and whatever you release on earth will have been released in heaven. 19 Again, I tell you the truth, if two of you on earth agree about whatever you ask, my Father in heaven will do it for you. 20 For where two or three are assembled in my name, I am there among them.”
