Mat Matthew, chapter The Gospel According to Matthew, chapter 5
Jesus taught that we should not be angry, and that we should quickly settle accounts with those whom we have wronged.
Matthew 5:21-26
“You have heard your religious teachers say that it was said {that Moses said} to your ancestors, ‘Do not murder anyone.’ This implied that if someone murders another person, the judge will condemn that person and sentence him to be executed {say that someone must execute him}. Exo 20:13; Deu 5:17; Mat 19:18; Mrk 10:19; Luk 18:20
