Deu Deuteronomy, chapter Book of Deuteronomy, chapter 13
Every word I command you, that shall you observe to perform; you shall not add to it nor diminish from it.Deu 4:1
If there shall arise among you a prophet, or a dreamer of dreams, and he give a sign or a wonder, Num 12:6and the sign or wonder cometh to pass, (yet,) should he speak with thee, saying, Let us go after the gods of the Gentiles whom thou hast not known, and let us worship them; Thou shalt not hearken to the words of that prophet or dreamer of dreams; for the Lord your God is proving you, to know whether you will love the Lord your God with all your heart and with all your soul. You shall walk after the Lord your God; Him shall ye fear, and keep His commandments, and be obedient to His Word, and serve Him, and keep close to His fear. Deu 8:6; Deu 10:20And that prophet, or dreamer of dreams, shall be put to death; for he hath spoken perversions against the Lord your God, who brought you out from the land of Mizraim, and delivered you from the house of bondage, to make you go astray from the path in which the Lord thy God hath commanded thee to walk; and so shalt thou put away the evil doer from the midst of thee.Deu 18:20
If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy covenant, or thy friend who is as thy soul, shall persuade thee in secret, saying: Let us go and worship the gods of the Gentiles whom thou hast not known, nor thy fathers, Deu 17:2; Deu 22:19gods of the nations round about you, nigh thee, or far off, from one end of the earth to the other; Thou shalt not consent to him, nor listen to his word, nor must thy eye have pity on him; thou shalt neither compassionate nor conceal him, Deu 19:13But killing thou shalt kill him; thy hand shall be upon him the first to kill him, and afterwards the hand of all the people; Deu 17:7And thou shalt stone him with stones that he die, because he sought to lead thee astray from the fear of the Lord thy God who brought thee out of the land of Mizraim, from the house of bondage; And all Israel will hear and be afraid, and not add to do this evil thing among thee.Deu 17:13; Deu 19:20
If thou hear in one of the cities which the Lord thy God will give thee to dwell in, saying: Men, sons of wickedness, have gone forth from among thee, and led away the inhabitants of their city, saying: Let us go and worship the gods of the nations which you have not known; Then shalt thou seek and search out, and fairly inquire; and, behold, such a thing is the truth, and this abomination is being done among thee, thou shalt smite the inhabitants of that city with the edge of the sword, and destroy it and all that is therein and its cattle by the edge of the sword; Deu 2:34And thou shalt gather all the spoil of it together into the midst of its street, and burn the city and the whole spoil thereof with fire entirely before the Lord thy God, and it shall be a desolate heap forever, it shall be builded no more; And nought of the accursed thing shall cleave to thy hand, that the Lord may turn away His anger from thee, and show mercy upon thee, and be loving towards thee, and increase thee, as He sware unto thy fathers; Deu 7:25When thou shalt be obedient to the Word of the Lord thy God, to observe all His commandments which I command thee this day, to do that which is right before the Lord thy God.
