Deuteronomy 21:4

And the elders of that city shall bring down the heifer into a rough valley, which has not been tilled and is not sown, and they shall slay the heifer in the valley.

And the elders of that city shall bring down the heifer unto a rough valley, which is neither eared nor sown, and shall strike off the heifer’s neck there in the valley:

The elders of that city shall bring the heifer down to a valley with running water, which is neither plowed nor sown, and shall break the heifer’s neck there in the valley.
