'Neck' in the Bible

For they shall be an ornament of grace unto thy head, and chains about thy neck.

Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart:

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

Bind them continually upon thine heart, and tie them about thy neck.

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