Deuteronomy 19:15
Clementine Vulgate · Berean Standard Bible
Non stabit testis unus contra aliquem, quidquid illud peccati, et facinoris fuerit : sed in ore duorum aut trium testium stabit omne verbum.
A lone witness is not sufficient to establish any wrongdoing or sin against a man, regardless of what offense he may have committed. A matter must be established by the testimony of two or three witnesses (note: Cited in Matthew 18:16 and 2 Corinthians 13:1).
