'Neck' in the Bible

For they shall be a chaplet of grace unto thy head, And chains about thy neck.

Let not kindness and truth forsake thee: Bind them about thy neck; Write them upon the tablet of thy heart:

So shall they be life unto thy soul, And grace to thy neck.

Bind them continually upon thy heart; Tie them about thy neck.

He that being often reproved hardeneth his neck Shall suddenly be destroyed, and that without remedy.
