Deuteronomy 21:2-4 ▼

2 Then thy elders and thy judges shall come forth, and they shall measure to the cities which are around him that is slain:

3 And it shall be that the city which is next to the slain man, even the elders of that city shall take a heifer which hath not been wrought with, and which hath not drawn in the yoke;

4 And the elders of that city shall bring down the heifer to a rough valley, which is neither tilled nor sown, and shall strike off the heifer's neck there in the valley;
