Mattityahu 13:10-16

And, approaching, the talmidim said to Rebbe, Melech HaMoshiach, Why in meshalim (parables) are you speaking to them? And Rebbe, Melech HaMoshiach answered them, Because to you it has been granted to have daas of the razim (mysteries) of the Malchut HaShomayim, but to those it has not been granted. For whoever has, will be given to him, and he will have an abundance. But whoever does not have, even what he has will be taken from him. For this reason in meshalim I am speaking to them, for while seeing they do not see, and hearing they do not hear, nor do they have binah (understanding). And in them is fulfilled the nevuah (prophecy) of Yeshayah HaNavi, saying, SHIMU SHAMOA VAL TAVINU UREU RAO VAL TEIDAU (In hearing you will hear and by no means understand, and seeing you will see and by no means perceive). HASHMEIN LEV HAAM HAZEH VAZNAV HACHBEID VEINAV HASHA, PEN YIREH VEINAV UVEAZNAV YISHMAH ULEVAVO YAVIN, VSHAV NRAFAH LOH. (For the heart of this people has been made dull, and [their] ears are hard of hearing, and their eyes are shut, lest they see with the their eyes and with [their] ears they hear, and with the lev (heart) they understand and they turn and I will give them refuah [healing]). But ashrey are your eyes, for they see, and your ears, for they hear.
