Deuteronomy 13:12-18 (New International Version)

 ¹² If you hear it said about one of the towns the LORD your God is giving you to live in ¹³ that wicked men have arisen among you and have led the people of their town astray, saying, "Let us go and worship other gods" (gods you have not known), ¹⁴ then you must inquire, probe and investigate it thoroughly. And if it is true and it has been proved that this detestable thing has been done among you, ¹⁵ you must certainly put to the sword all who live in that town. Destroy it completely, ^[a] both its people and its livestock. ¹⁶ Gather all the plunder of the town into the middle of the public square and completely burn the town and all its plunder as a whole burnt offering to the LORD your God. It is to remain a ruin forever, never to be rebuilt. ¹⁷ None of those condemned things ^[b] shall be found in your hands, so that the LORD will turn from his fierce anger; he will show you mercy, have compassion on you, and increase your numbers, as he promised on oath to your forefathers, ¹⁸ because you obey the LORD your God, keeping all his commands that I am giving you today and doing what is right in his eyes.
