Essential Bible Verses for Dealing with Difficult People

I have been struggling with my attitude towards someone lately, and wanted to collect some scriptures to help me with that. 

1. If possible, so far as it depends on you, live at peace with all. (Romans 12:18)
2. Do unto others as you would have them do unto you, for this is the Law and the Prophets. (Matthew 7:12)
3. Judge not, so that you will not be judged.  (Matthew 7:1)
4. Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person. (Colossians 4:6)
5. See that no one repays evil for evil, but always seek to do good to one another and to everyone. (1 Thessalonians 5:15)
6. Above all, keep loving one another earnestly, for love covers a multitude of sins. (1 Peter 4:8)
7. Do not repay evil for evil or slander for slander, but on the contrary, bless, for to this you were called, that you may obtain a blessing. (1 Peter 3:9)
8. Have nothing to do with foolish, ignorant controversies; knowing that they breed quarrels. And the Lord's servant must not quarrel but be kind to everyone, able to teach, patient. (2 Timothy 2:23-24)
9.  Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you. (Ephesians 4:32)

   So many good candidates for this list.
