'Hair' in the Bible

and standing behind at his feet, weeping, she began to wet his feet with her tears, and wiped them with the hair of her head, and kissed his feet, and anointed them with the ointment.

And turning to the woman, he said unto Simon, Seest thou this woman? I entered into thy house, thou gavest me no water for my feet: but she hath wetted my feet with her tears, and wiped them with her hair.

And not a hair of your head shall perish.
