Bible: Deut 13:6-9
False Prophets in the Family
13:6 Suppose your own full brother, 1 your son, your daughter, your beloved wife, or your closest friend should seduce you secretly and encourage you to go and serve other gods 2 that neither you nor your ancestors 3 have previously known, 4 13:7 the gods of the surrounding people (whether near you or far from you, from one end of the earth 5 to the other). 13:8 You must not give in to him or even listen to him; do not feel sympathy for him or spare him or cover up for him. 13:9 Instead, you must kill him without fail! 6 Your own hand must be the first to strike him, 7 and then the hands of the whole community.
