"If there will have arisen in your midst a prophet, or someone who claims that he had seen a dream, and if he will have predicted sign and portent,
and if what he has spoken happens, and he says to you, 'Let us go and follow strange gods,' which you have not known, 'and let us serve them,'
you shall not listen to the words of that prophet or dreamer. For the Lord your God is testing you, so that it may become clear whether or not you love him with all your heart and with all your soul.
