Deuteronomy 13:2-4

Young's Literal Translation

² and the sign and the wonder hath come which he hath spoken of unto thee, saying, Let us go after other gods (which thou hast not known), and serve them,

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.
