'Head' in the Bible

When I heard this thing, I tore my garment and my robe, and plucked off the hair of my head and of my beard, and sat down confounded.

and I said, "My God, I am ashamed and blush to lift up my face to you, my God; for our iniquities have increased over our head, and our guiltiness has grown up to the heavens.
