Isaiah 29:11,12

And the vision, &c.— These words set forth the consequence of the common blindness of the whole Jewish nation, learned and unlearned, teacher and people; namely, their universal incapacity to interpret and to understand the word of God, especially the prophetic word; which incapacity Isaiah exposes in a parable no less plain than beautiful. How remarkably this prophesy has been and is fulfilled, we learn abundantly from those teachers of the Jews to whom the prophetic vision is to this day a sealed book, and of which the people, incapable of gaining instruction from their teachers, are equally ignorant, each being alike in gross and judicial darkness.
