'Neck' in the Bible

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

And all the elders of that city, who are nearest unto the slain man, shall wash their hands over the heifer whose neck was broken in the valley;

therefore shalt thou serve thine enemies that Jehovah shall send against thee, in hunger, and in thirst, and in nakedness, and in want of all things: and he shall put a yoke of iron upon thy neck, until he have destroyed thee.

For I know thy rebellion, and thy stiff neck: behold, while I am yet alive with you this day, ye have been rebellious against Jehovah; and how much more after my death?
