“Jesus said.

‘To you

It has been given

To know the secrets

Of the kingdom

Of God.

But to others,

I speak in parables.

Thus,

Looking,

They may not perceive!

Listening,

They may not understand!’”

ὁ δὲ εἶπεν Ὑμῖν δέδοται γνῶναι τὰ μυστήρια τῆς βασιλείας τοῦ Θεοῦ, τοῖς δὲ λοιποῖς ἐν παραβολαῖς, ἵνα βλέποντες μὴ βλέπωσιν καὶ ἀκούοντες μὴ συνιῶσιν.

Luke indicated that Jesus said (ὁ δὲ εἶπεν) to his disciples that they would be able to understand the secrets (Ὑμῖν δέδοται γνῶναι τὰ μυστήρια) of the kingdom of God (τῆς βασιλείας τοῦ Θεοῦ).  But to others (τοῖς δὲ λοιποῖς), he would be speaking in parables or riddles (ἐν παραβολαῖς).  Thus, these people might look (ἵνα βλέποντες), but not see (μὴ βλέπωσιν).  They might listen (καὶ ἀκούοντες), but not understand (μὴ συνιῶσιν).  This response of Jesus about the meaning of parables can be found in all 3 synoptic gospels, Mark, chapter 4:11-12, and Matthew, chapter 13:11-15, and here.  Matthew and Mark also said that Jesus told his disciples that they had been given knowledge concerning the secret mysteries about the kingdom of heaven or the kingdom of God.  However, this was not granted to others.  Matthew had Jesus explain that those who had more knowledge, even more abundant knowledge would be given to them.  However, those who had nothing, even what little they had would be taken away.  The reason that Jesus spoke in parables was that some people might see, but not perceive what they saw, while other people might hear but not understand what they have heard.  For people outside their disciple group, everything was still in parables or riddles.  Only those on the inside would understand these parables, while those outside the inner circle of Jesus would not understand these riddles.  This was almost like a gnostic interpretation of knowledge, where only the elite insiders had a true secret knowledge about the mysteries and the kingdom of God and heaven.  Matthew also had a long citation from Isaiah, chapter 6:9-10, about the people unable to understand, while Luke, and Mark had only a short summary statement.  Isaiah told the Israelite people that they were listening without comprehending.  They were looking without understanding.  Their hearts were dull and their eyes and ears were closed.  They were experiencing and listening, but they could not hear or understand.  Do you understand what you see and hear?
