Deuteronomy 13

1 If there rise in the midst of thee a prophet or one that saith he hath dreamed a dream, and he foretell a sign and a wonder, 2 And that come to pass which he spoke, and he say to thee: Let us go and follow strange gods, which thou knowest not, and let us serve them: 3 Thou shalt not hear the words of that prophet or dreamer: for the Lord your God trieth you, that it may appear whether you love him with all your heart, and with all your soul, or not.
