Matthew 13:13-17 New Revised Standard Version (NRSV)
13 The reason I speak to them in parables is that ‘seeing they do not perceive, and hearing they do not listen, nor do they understand.’ 14 With them indeed is fulfilled the prophecy of Isaiah that says:
‘You will indeed listen, but never understand,
16 But blessed are your eyes, for they see, and your ears, for they hear. 17 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.
