Deuteronomy 13:6-8

New Revised Standard Version, Anglicised Catholic Edition

⁶ If anyone secretly entices you—even if it is your brother, your father’s son or^[a] your mother’s son, or your own son or daughter, or the wife you embrace, or your most intimate friend—saying, ‘Let us go and worship other gods’, whom neither you nor your ancestors have known, ⁷ any of the gods of the peoples that are around you, whether near you or far away from you, from one end of the earth to the other, ⁸ you must not yield to or heed any such persons. Show them no pity or compassion and do not shield them.
