Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger;  for the anger of man does not produce the righteousness of God. (James 1:18, 19 )

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.
(Romans 12: 17, 18)
