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.
