'Head' in the Bible

And himself is the head of the body -- the assembly -- who is a beginning, a first-born out of the dead, that he might become in all things -- himself -- first,

and ye are in him made full, who is the head of all principality and authority,

and not holding the head, from which all the body -- through the joints and bands gathering supply, and being knit together -- may increase with the increase of God.
