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.

John 16:25

16:25 “I have told you these things in obscure figures of speech; a time is coming when I will no longer speak to you in obscure figures, but will tell you plainly about the Father.
