so that looking shall they look and not see, and on hearing shall they hear and not understand; lest will they repentance do and it will them forgiven to be. (Yeshayah 6, 9-10)
and he had blind made their eyes, hard made their heart, so that they should not see with the eyes, and understand with the heart, and repentance do, and I shall them heal. (Yeshayah 6, 9, 10)
as it stands written: Hashem did them give a spirit of deep sleep, eyes, not to the see, and ears, not to the hear, until to the today's day. (Yeshayah 29, 10; Deuteronomy 29, 3.)
therefore will I always be ready you (PL) to remind about the these things, although you (PL) know them and are established firmly in the truth, which is with (you (PL)).
