'Hairs of My Head' in the Bible

For there have closed in upon me, misfortunes beyond number, Mine iniquities have overtaken me, and I cannot see, They have become more than the hairs of my head, And, my courage, hath forsaken me!

More than the hairs of my head, Are they who hate me without cause, - Firmer than my bones, Are they who are my foes for false cause, - What I had not plundered, then, had I to restore.
