Yea, thou heardest not; yea, thou knewest not yea, from that time that thine ear was not opened,.... This, as Kimchi rightly observes, is said by way of reproof; showing that they were so far from knowing these things before the prophecy of them was given out, that when it was, they did not hearken or listen to them; they did not understand them, nor receive and embrace them, but turned a deaf ear to them; their hearts being hardened, and they given up blindness of mind; which was the case of the Jews, even when the Messiah, the antitype of Cyrus, came, and there was a more clear revelation of Gospel truths, as was foretold, Isa 6:9.
To this sense is the Targum,"yea, thou has not heard the words of the prophets; yea, thou hast not received the doctrine of the law; yea, thou hast not inclined thine ear to the words of the blessings and curses of the covenant I made with thee at Horeb:''for I knew that thou wouldest deal very treacherously: with God, and with one another, as they did; and were, as Jeremiah calls them, an assembly of treacherous men; and especially so they were in Christ's time, and to him; one of his own disciples treacherously betrayed him into the hands of the Jews, and they delivered him into the hands of the Gentiles to be crucified and slain; all which he knew before hand, Joh 6:64.
