Mark 4:9-12

9And he said, He that has ears to hear, let him hear.

10And when he was alone, those about him with the twelve asked him [as to] the parables.

11And he said to them, To you is given [to know] the mystery of the kingdom of 1God; but to them who are without, all things are done in parables,

12that beholding they may behold and not see, and hearing they may hear and not understand, lest it may be, they should be converted and they should be forgiven.
