Matthew 13:17

13:17 For I tell you the truth, ¹  many prophets and righteous people longed to see ²  what you see but did not see it, and to hear what you hear but did not hear it.

Matthew 13:15

13:15 For the heart of this people has become dull;

they are hard of hearing,

and they have shut their eyes,

so that they would not see with their eyes

and hear with their ears

and understand with their hearts

and turn, and I would heal them.’ ³ 

[13:17]  ¹ tn Grk “truly (ἀμήν, amhn) I say to you.”

[13:17]  ² sn This is what past prophets and righteous people had wanted very much to see, yet the fulfillment had come to the disciples. This remark is like 1 Pet 1:10-12 or Heb 1:1-2.

[13:15]  ³ sn A quotation from Isa 6:9-10. Thus parables both conceal or reveal depending on whether one is open to hearing what they teach.
