'Head' in the Bible

We asked them their names also, to certify thee, that we might write the names of the men that were at the head of them.

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

and I said, O my God, I am ashamed and blush to lift up my face to thee, my God; for our iniquities are increased over our head, and our guiltiness is grown up unto the heavens.
