'Head' in the Bible

The waters were circling round me, even to the neck; the deep was about me; the sea-grass was twisted round my head.

And the Lord God made a vine come up over Jonah to give him shade over his head. And Jonah was very glad because of the vine.

Then when the sun came up, God sent a burning east wind: and so great was the heat of the sun on his head that Jonah was overcome, and, requesting death for himself, said, Death is better for me than life.
