Deuteronomy 21:2-4

New Life Version

² then your leaders and judges will go out and see how far it is to the cities that are around the dead man. ³ The leaders of the city that is nearest to the dead man will take a young cow from the cattle. The cow must never have been worked or pulled a plow. ⁴ The leaders of that city will bring the young cow down to a valley with flowing water, which has not been plowed or planted. They will break the cow’s neck there in the valley.
