Deuteronomy 13:14-16

New Catholic Bible

¹⁴ there are evil men who have come out from among you and who have misled the inhabitants of the city saying, “Let us go and serve other gods whom we have not previously known,” ¹⁵ then you will inquire, and probe, and investigate it thoroughly. If it is clearly proven that this detestable thing has been done among you, ¹⁶ you are to put the inhabitants of that city to the sword and you are to demolish it. Destroy everything in it, even killing the cattle with the edge of the sword.
