Forgive others and put away all bitterness!

“Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice.” (Eph. 4:31 ESV)

Strive for peace with everyone

“Strive for peace with everyone, and for the holiness without which no one will see the Lord. See to it that no one fails to obtain the grace of God; that no “root of bitterness” springs up and causes trouble, and by it many become defiled.” (Heb. 12:14-15 NIV)

Forgive others their trespasses 

“Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.” (Eph. 4:32 ESV)

“And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses.” (Mark 11:25 ESV)

“For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses.” (Matt. 6:14-15 ESV)

Therefore…

“Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” Do not be overcome by evil, but overcome evil with good.” (Rom. 12:17-21 ESV)
