ISB ~ Matthew 5 v21

You shall not kill:Jesus reaffirms that murder is unlawful (Ex 20:13; Deut 5:17) but introduces a new dimension to the civil law. Not only acts of murder but even personal anger (5:22) and private slander (5:22) constitute a violation of the New Law. Degrees of personal guilt are illustrated (5:22) by an escalating movement from a local court verdict (“judgment”), to the Jewish Sanhedrin (“council”), to eternal punishment (“hell”). At each step, the judgment corresponds to the severity of the sin (CCC 2302).
