I will open my mouth in a parable.  I will utter dark sayings of old.  Psalm 78:2  written 1000 b.c.

Jesus spoke all these things to the crowd in parables.  He did not say anything to them without using a parable, so was fulfilled what was spoken through the prophet:  "I will open my mouth in parables.  I will utter things hidden since the creation of the world."  Matthew 13:34-35

This is another example of his eternal nature.
