'Hair' in the Bible

And she saith, 'Let, I pray thee, the king remember by Jehovah thy God, that the redeemer of blood add not to destroy, and they destroy not my son;' and he saith, 'Jehovah liveth; if there doth fall of the hair of thy son to the earth.'

and in his polling his head -- and it hath been at the end of year by year that he polleth it, for it is heavy on him, and he hath polled it -- he hath even weighed out the hair of his head -- two hundred shekels by the king's weight.
