Context Reading
1If someone is found slain in the land which Yahweh your God gives you to possess, lying in the field, and it isn’t known who has struck him, 2then your elders and your judges shall come out, and they shall measure to the cities which are around him who is slain. 3It shall be that the elders of the city which is nearest to the slain man shall take a heifer of the herd, which hasn’t been worked with and which has not drawn in the yoke.
