Psalms 49:4

49:4 I will learn a song that imparts wisdom;

I will then sing my insightful song to the accompaniment of a harp.

Matthew 13:13

13:13 For this reason I speak to them in parables: Although they see they do not see, and although they hear they do not hear nor do they understand.

Matthew 13:34-35

The Purpose of Parables

13:34 Jesus spoke all these things in parables to the crowds; he did not speak to them without a parable. 13:35 This fulfilled what was spoken by the prophet:

“I will open my mouth in parables,

I will announce what has been hidden from the foundation of the world.”
