Why cloak Bible prophecies in Symbols?
Luke 8 :10 And He said, "To you it has been given to know the mysteries of the kingdom of God, but to the rest it is given in parables, that 'Seeing they may not see, And hearing they may not understand.'

Many of the apocalyptic prophecies were given while the prophets were in a hostile foreign land. One reason God cloaked the prophecies in symbols was to protect the messages.
