'Head' in the Bible

I sent them to Iddo, the head of the place called Casiphia, and I placed in their mouths what words to say to Iddo and his brothers the temple servants in Casiphia, to send to us ministers for the house of our God.

When I heard this I tore my garment and my robe, and I pulled the hair out from my head and beard, and I sat appalled.
