Deuteronomy 13:5, 9

But that prophet or that dreamer of dreams shall be put to death, because he has counseled rebellion against the LORD your God who brought you from the land of Egypt and redeemed you from the house of slavery, to draw you away from the way in which the LORD your God has commanded you to walk. So you shall remove the evil from among you.

Instead, you shall most certainly execute him; your hand shall be first [to be raised] against him to put him to death, and afterwards the hand of all the people.
