'Heads' in the Bible

He is gone up to Bajith, and to Dibon, the high places, to weep: Moab shall howl over Nebo, and over Medeba: on all their heads shall be baldness, and every beard cut off.

And the ransomed of the LORD shall return, and come to Zion with songs and everlasting joy upon their heads: they shall obtain joy and gladness, and sorrow and sighing shall flee away.
