Mark 4:2

And he called them unto him, and said unto them in parables, How can Satan cast out Satan?

And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables:

All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them: 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.

And the disciples came, and said unto him, Why speakest thou unto them in parables?

And he spake many things unto them in parables, saying, Behold, a sower went forth to sow;

Jesus answered them, and said, My doctrine is not mine, but his that sent me. If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.

And he said unto them in his doctrine, Beware of the scribes, which love to go in long clothing, and love salutations in the marketplaces,

And with many such parables spake he the word unto them, as they were able to hear it. But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples.

And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine:

I will incline mine ear to a parable: I will open my dark saying upon the harp.

I will open my mouth in a parable: I will utter dark sayings of old:

The high priest then asked Jesus of his disciples, and of his doctrine.
