Deuteronomy Chapter 18 World English Bible
This shall be the priests' due from the people, from those who offer a sacrifice, whether it be ox or sheep, that they shall give to the priest the shoulder, and the two cheeks, and the maw.
There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, or a sorcerer,
according to all that you desired of Yahweh your God in Horeb in the day of the assembly, saying, Let me not hear again the voice of Yahweh my God, neither let me see this great fire any more, that I not die.
But the prophet, who shall speak a word presumptuously in my name, which I have not commanded him to speak, or who shall speak in the name of other gods, that same prophet shall die.
when a prophet speaks in the name of Yahweh, if the thing doesn't follow, nor happen, that is the thing which Yahweh has not spoken: the prophet has spoken it presumptuously, you shall not be afraid of him.
