Psalm 78:2 (KJV) I will open my mouth in a parable: I will utter dark sayings of old:
3 Which we have heard and known, and our fathers have told us.
4 We will not hide them from their children, shewing to the generation to come the praises of the Lord, and his strength, and his wonderful works that he hath done.
Matthew 13:34 All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them:
35 That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world.
