What does the Bible say about enemies and injustice?

“Don’t seek revenge yourselves, beloved, but give place to God’s wrath. For it is written, “Vengeance belongs to me; I will repay, says the Lord.” Therefore “If your enemy is hungry, feed him. If he is thirsty, give him a drink; for in doing so, you will heap coals of fire on his head.” Don’t be overcome by evil, but overcome evil with good.”

““But I tell you who hear: love your enemies, do good to those who hate you, bless those who curse you, and pray for those who mistreat you.”

“The righteous cry, and the LORD hears, and delivers them out of all their troubles.”

“But I tell 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,”

“If your enemy is hungry, give him food to eat. If he is thirsty, give him water to drink; for you will heap coals of fire on his head, and the LORD will reward you.”

“not rendering evil for evil or insult for insult; but instead blessing, knowing that you were called to this, that you may inherit a blessing.”

“Rest in the LORD, and wait patiently for him. Don’t fret because of him who prospers in his way, because of the man who makes wicked plots happen. Cease from anger, and forsake wrath. Don’t fret; it leads only to evildoing. For evildoers shall be cut off, but those who wait for the LORD shall inherit the land.”

“Bless those who persecute you; bless, and don’t curse.”
