New American Standard Bible (NASB)
Romans 12
18 If possible, so far as it depends on you, be at peace with all men.
19 Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, "Vengeance is Mine, I will repay," says the Lord.
20 "But if your enemy is hungry, feed him, and if he is thirsty, give him a drink; for in so doing you will heap burning coals on his head."
21 Do not be overcome by evil, but overcome evil with good.
Romans 13
1 Every person is to be in subjection to the governing authorities. For there is no authority except from God, and those which exist are established by God.
2 Therefore whoever resists authority has opposed the ordinance of God; and they who have opposed will receive condemnation upon themselves.
3 For rulers are not a cause of fear for good behavior, but for evil. Do you want to have no fear of authority? Do what is good and you will have praise from the same;
4 for it is a minister of God to you for good. But if you do what is evil, be afraid; for it does not bear the sword for nothing; for it is a minister of God, an avenger who brings wrath on the one who practices evil.
5 Therefore it is necessary to be in subjection, not only because of wrath, but also for conscience’ sake.
6 For because of this you also pay taxes, for rulers are servants of God, devoting themselves to this very thing.
7 Render to all what is due them: tax to whom tax is due; custom to whom custom; fear to whom fear; honor to whom honor.
