Devarim 21:1-3

Orthodox Jewish Bible

21 If one be found slain in ha’adamah which Hashem Eloheicha giveth thee to possess it, lying in the sadeh, and it be not known who hath slain him;

² Then thy zekenim and thy shofetim shall come forth, and they shall measure unto the towns which are round about him that is slain;

³ And it shall be, that the town which is next unto the slain man, even the zekenim of that town shall take a heifer, which hath not been worked with, and which hath not pulled the ol (yoke);
