'Neck' in the Bible

and bring the heifer down to a wadi with flowing water, to a valley that is neither plowed nor sown. There at the wadi they are to break the heifer's neck.

and all the elders of that city nearest the corpse must wash their hands over the heifer whose neck was broken in the valley.

instead in hunger, thirst, nakedness, and poverty you will serve your enemies whom the Lord will send against you. They will place an iron yoke on your neck until they have destroyed you.
