"If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder ... that prophet, or that dreamer of dreams, shall be put to death." Deuteronomy 13:1-5
Under this law alone, many people would have been put to death. John Lennon, Spinoza, Isaac Newton, Moses, Jesus ... all guilty of being either a prophets and dreamers if judged from the eyes of the ancient Israelites. Luckily, these eyes are long closed.
Deuteronomy, Chapter 13 is a sermon to the Israelites on the evils of new ideas, aka heresy.
A few verses later (13:6-10) Moses spells it out clearly: ""If thy brother ... or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods ... Thou shalt not consent unto him ... neither shall thine eye pity him ... But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people."
Today of course, we ignore all of Moses' advice in this chapter, but I must ask you. If the Bible is a manual for morality, what is it that causes us to ignore this verse but find wisdom in a verse like that in Leviticus that says to "Love your neighbor."?
