Deuteronomy 13:6

This term being applied very loosely in all Eastern countries (Genesis 20:13), other expressions are added to intimate that no degree of kindred, however intimate, should be allowed to screen an enticer to idolatry-which was a breach of the national covenant-to conceal his crime or protect his person. Piety and duty must overcome affection or compassion, and an accusation must be lodged before a magistrate.
