Deuteronomy 21:3-4 ▼

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;
