'Hairs of My Head' in the Bible

for innumerable evils have encompassed me around. My iniquities have overtaken me, so that I am not able to look up. They are more than the hairs of my head, and my heart has failed me.

Those who hate me without a cause are more than the hairs of my head. Those who would cut me off, being my enemies wrongfully, are mighty. That which I took not away I have to restore.
