20: But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
21: And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?
22: When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
So you killed your leader, and now we don’t have to be afraid of him? Because by your terms, if you have not killed him, you have displeased the Lord. (And note, the bible says “the” Lord)
