And the prophecy of Isaiah is fulfilled on them, which says, “In hearing you will hear and not understand, not ever; and seeing you will see yet not perceive, not ever.
Son of man, you dwell in the midst of a rebellious house. They have eyes to see, but they do not see; ears are to them to hear, but they do not hear; for they are a rebellious house.
that seeing they may see and not perceive; and hearing they may hear, and not understand, that not ever they should convert, and the sins be remitted to them. Isa. 6:9, 10
And He said, To you it has been given to know the mysteries of the kingdom of God, but to the rest in parables, that seeing they might not see, and hearing, they might not understand. Isa. 6:9
But their thoughts were hardened, for until this very day the same veil remains on the reading of the Old Covenant, not being unveiled, that it is being done away in Christ.
