ISB ~ 2 Corinthians 13 v1
two or three witnesses:Judicial criteria drawn from Deut 17:6 and 19:15.
• The Mosaic Law forbade Israel to punish crimes on the basis of a single witness. Accused persons were thus assured a fair criminal process and that punishment would not be administered without credible and corroborating testimony. Paul, like Jesus, applies this principle in a New Covenant context (Mt 18:16-17). He thus assures the Corinthians that detractors will not be expelled from their fellowship and liturgy without a just examination of the facts (1 Tim 5:19). Even so, Paul is ready to punish disobedience if necessary (10:6; 13:2). See note on 1 Cor 5:13.
