[10] The disciples came to him and asked, “Why do you speak to the people in parables?” [11] He replied, “Because the knowledge of the secrets of the kingdom of heaven has been given to you, but not to them. [12] Whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them. [13] This is why I speak to them in parables: “Though seeing, they do not see; though hearing, they do not hear or understand. [14] In them is fulfilled the prophecy of Isaiah: “ ‘You will be ever hearing but never understanding; you will be ever seeing but never perceiving. [15] For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.’ [16] But blessed are your eyes because they see, and your ears because they hear. [17] For truly I tell you, many prophets and righteous people longed to see what you see but did not see it, and to hear what you hear but did not hear it.
