Deuteronomy 13:14

11 And all Israel shall hear, and fear, and shall do not more any such wickedness as this is in the midst of thee.

12 If thou shalt hear tell concerning one of thy cities, which Jehovah thy God giveth thee to dwell there, saying,

13 Certain base fellows are gone out from the midst of thee, and have drawn away the inhabitants of their city, saying, Let us go and serve other gods, which ye have not known;

14 then shalt thou inquire, and make search, and ask diligently; and, behold, if it be truth, and the thing certain, that such abomination is wrought in the midst of thee,

15 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.

16 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, unto Jehovah thy God: and it shall be a heap for ever; it shall not be built again.

17 And there shall cleave nought of the devoted thing to thy hand; that Jehovah may turn from the fierceness of his anger, and show thee mercy, and have compassion upon thee, and multiply thee, as he hath sworn unto thy fathers;
