'Hair' in the Bible

and standing behind [him] at his feet weeping, she began to wet his feet with [her] tears and was wiping [them] with the hair of her head and was kissing his feet and anointing [them] with the perfumed oil.

And turning toward the woman, he said to Simon, "Do you see this woman? I entered into your house. You did not give me water for [my] feet, but she wet my feet with [her] tears and wiped [them] with her hair.

Even a hair of your head will never perish!
