In the world of Intelligence, "need to know" is a basic principle, so everyone does not have "Top Secret" clearance, only those with the need to know. That is wisdom, otherwise the enemies of a country will know exactly what is being discussed or planned, and sabotage it.
When Jesus began speaking in parables, His intention was to conceal spiritual truths from His enemies, and only reveal them to His disciples. So "seeing they would not see, and hearing they would not understand" because they had rejected Him. That was divine wisdom, since the principle was to not throw pearls before swine, or give dogs that which was holy.
