Deuteronomy 21:2 DBY

¹  If one be found slain in the land which Jehovah thy God giveth thee to possess, lying in the field, [and] it be not known who hath smitten him,

²  then thine elders and thy judges shall go forth, and they shall measure unto the cities which are round about him that is slain;

³  and the city that is nearest unto him that is slain, even the elders of that city shall take a heifer that hath not been wrought with, that hath not drawn in the yoke;

⁴  and the elders of that city shall bring down the heifer unto an ever-flowing watercourse, which is not tilled, nor is it sown, and shall break the heifer's neck there in the watercourse;
