Matthew 13:13-14

13:13 For this reason I speak to them in parables: Although they see they do not see, and although they hear they do not hear nor do they understand. 13:14 And concerning them the prophecy of Isaiah is fulfilled that says:

‘You will listen carefully yet will never understand,

you will look closely yet will never comprehend.

Matthew 13:51

13:51 “Have you understood all these things?” They replied, “Yes.”
