And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
TSK
Treasury of Scripture Knowledge references in ASV.
And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
that seeing they may see, and not perceive; and hearing they may hear, and not understand; lest haply they should turn again, and it should be forgiven them.
For this cause they could not believe, for that Isaiah said again,
according as it is written, God gave them a spirit of stupor, eyes that they should not see, and ears that they should not hear, unto this very day.
