"He that sacrificeth unto any god, save unto the Lord only, he shall be utterly destroyed." Exodus 22:20
"If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers; Namely, of the gods of the people which are round about you, nigh unto thee, or far off from thee, from the one end of the earth even unto the other end of the earth; Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him: But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people. And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the Lord thy God, which brought thee out of the land of Egypt, from the house of bondage." Deuteronomy 13:6-10
"And they entered into a covenant to seek the Lord God of their fathers with all their heart and with all their soul; That whosoever would not seek the Lord God of Israel should be put to death, whether small or great, whether man or woman." 2 Chronicles 15:12-13
"Certain men, the children of Belial, are gone out from among you, and have withdrawn the inhabitants of their city, saying, Let us go and serve other gods, which ye have not known; Then shalt thou enquire, and make search, and ask diligently; and, behold, if it be truth, and the thing certain, that such abomination is wrought among you; Thou shalt surely smite the inhabitants of that city with the edge of the sword, destroying it utterly, and all that is therein, and the cattle thereof, with the edge of the sword. And thou shalt gather all the spoil of it into the midst of the street thereof, and shalt burn with fire the city, and all the spoil thereof every whit, for the Lord thy God: and it shall be an heap for ever; it shall not be built again. And there shall cleave nought of the cursed thing to thine hand: that the Lord may turn from the fierceness of his anger, and shew thee mercy, and have compassion upon thee, and multiply thee, as he hath sworn unto thy fathers; When thou shalt hearken to the voice of the Lord thy God, to keep all his commandments which I command thee this day, to do that which is right in the eyes of the Lord thy God." Deuteronomy 13:13-19
"If there be found among you, within any of thy gates which the Lord thy God giveth thee, man or woman, that hath wrought wickedness in the sight of the Lord thy God, in transgressing his covenant, And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of the host of heaven, which I have not commanded; And it be told thee, and thou hast heard of it, and enquired diligently, and, behold, it be true, and the thing certain, that such abomination is wrought in Israel: Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, even that man or that woman, and shalt stone them with stones, till they die." Deuteronomy 17:2-5
"And Israel abode in Shittim, and the people began to commit whoredom with the daughters of Moab. And they called the people unto the sacrifices of their gods: and the people did eat, and bowed down to their gods. And Israel joined himself unto Baalpeor: and the anger of the Lord was kindled against Israel. And the Lord said unto Moses, Take all the heads of the people, and hang them up before the Lord against the sun, that the fierce anger of the Lord may be turned away from Israel. And Moses said unto the judges of Israel, Slay ye every one his men that were joined unto Baalpeor. And, behold, one of the children of Israel came and brought unto his brethren a Midianitish woman in the sight of Moses, and in the sight of all the congregation of the children of Israel, who were weeping before the door of the tabernacle of the congregation. And when Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from among the congregation, and took a javelin in his hand; And he went after the man of Israel into the tent, and thrust both of them through, the man of Israel, and the woman through her belly.So the plague was stayed from the children of Israel. And those that died in the plague were twenty and four thousand." Numbers 25:1-9
