'Neck' in the Bible

and are to lead the heifer to a flowing stream in a valley that has never been tilled or planted. They are to break the heifer's neck there.

All the elders of the city nearest the dead body are to wash their hands over the heifer whose neck was broken in the valley,

you'll serve your enemies whom the LORD your God will send against you. You will serve in famine and in drought, in nakedness, and in lack of everything. They'll set a yoke of iron upon your neck until they have exterminated you.
