Deuteronomy 13:3-5

Young's Literal Translation

³ thou dost not hearken unto the words of that prophet, or unto that dreamer of the dream, for Jehovah your God is trying you, to know whether ye are loving Jehovah your God with all your heart, and with all your soul;

⁴ after Jehovah your God ye walk, and Him ye fear, and His commands ye keep, and to His voice ye hearken, and Him ye serve, and to Him ye cleave.

⁵ `And that prophet, or that dreamer of the dream, is put to death, for he hath spoken apostacy against Jehovah your God (who is bringing you out of the land of Egypt, and hath ransomed you out of a house of servants), to drive you out of the way in which Jehovah thy God hath commanded thee to walk, and thou hast put away the evil thing from thy midst.
