Then your elders and your judges shall come forth, and they shall measure to the cities which are round about him that is slain:
If one be found slain in the land which the LORD your God gives you to possess it, lying in the field, and it be not known who has slain him:
And it shall be, that the city which is nearest to the slain man, even the elders of that city shall take a heifer, which has not been worked with, and which has not pulled in the yoke;
