'Head' in the Bible

"Shave your head and cut off your locks as you mourn your beloved children. Make yourself bald as an eagle, because they will go from you into exile!"

The breaker is come up before them: they have broken up, and have passed through the gate, and are gone out by it: and their king shall pass before them, and the LORD on the head of them.

With what am I to come before the Lord and go with bent head before the high God? am I to come before him with burned offerings, with young oxen a year old?
