1 Corinthians 6:4-8 If then you have judgments concerning things pertaining to this life, do you appoint those who are least esteemed by the church to judge? I say this to your shame. Is it so, that there is not a wise man among you, not even one, who will be able to judge between his brethren? But brother goes to law against brother, and that before unbelievers! Now therefore, it is already an utter failure for you that you go to law against one another. Why do you not rather accept wrong? Why do you not rather let yourselves be cheated? No, you yourselves do wrong and cheat, and you do these things to your brethren!
Matthew 5:38-42 "You have heard that it was said, 'An eye for an eye and a tooth for a tooth.' But I tell you not to resist an evil person. But whoever slaps you on your right cheek, turn the other to him also. If anyone wants to sue you and take away your tunic, let him have your cloak also. And whoever compels you to go one mile, go with him two. Give to him who asks you, and from him who wants to borrow from you do not turn away.
Romans 12:14 Bless those who persecute you; bless and do not curse.
Romans 12:19-21 Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, "Vengeance is Mine, I will repay," says the Lord. Therefore" If your enemy is hungry, feed him; If he is thirsty, give him a drink; For in so doing you will heap coals of fire on his head." Do not be overcome by evil, but overcome evil with good.
1 Corinthians 6:1 Dare any of you, having a matter against another, go to law before the unrighteous, and not before the saints?
Genesis 13:8-9 So Abram said to Lot, “Please let there be no strife between you and me, and between my herdsmen and your herdsmen; for we are brethren. Is not the whole land before you? Please separate from me. If you take the left, then I will go to the right; or, if you go to the right, then I will go to the left.”
Deuteronomy 32:35 Vengeance is Mine, and recompense; Their foot shall slip in due time; For the day of their calamity is at hand, And the things to come hasten upon them.’
Matthew 5:20 For I say to you, that unless your righteousness exceeds therighteousness of the scribes and Pharisees, you will by no means enter the kingdom of heaven.
Luke 6:34-35 And if you lend to those from whom you hope to receive back, what credit is that to you? For even sinners lend to sinners to receive as much back. But love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. For He is kind to the unthankful and evil.
Romans 12:17 Repay no one evil for evil. Have regard for good things in the sight of all men.
