Deuteronomy 13:2-4

Darby Translation

² and the sign or the wonder come to pass that he told unto thee, when he said, Let us go after other gods, whom thou hast not known, and let us serve them,

³ —thou shalt not hearken unto the words of that prophet, or that dreamer of dreams; for Jehovah your God proveth you, to know whether ye love Jehovah your God with all your heart and with all your soul.

⁴ Ye shall walk after Jehovah your God, and ye shall fear him, and his commandments shall ye keep, and his voice shall ye hear; and ye shall serve him, and unto him shall ye cleave.
