In context
8Finally, all of you, be like-minded and sympathetic, love as brothers, be tenderhearted and humble. 9Do not repay evil with evil or insult with insult, but with blessing, because to this you were called so that you may inherit a blessing. 10For, 11He must turn from evil and do good; 12For the eyes of the Lord are on the righteous, 13Who can harm you if you are zealous for what is good?
