'Symbol' in the Bible

Because of this, the woman ought to have [a symbol of] authority on her head, on account of the angels.

which [was] a symbol for the present time, in which both the gifts and sacrifices which were offered were not able to perfect the worshiper with respect to the conscience,

having reasoned that God [was] able even to raise [him] from the dead, from which he received him back also as a symbol.
