John Chrysostom

"And when they agreed not among themselves, they departed, after that Paul had spoken one word, Well spake the Holy Ghost by Esaias the prophet unto our fathers, saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive: for the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them." But when they departed, as they were opposed to each other, then he reproaches them, not because he wished to reproach those that believed not, but to confirm these that believed. "Well said Esaias," says he to them. So that to the Gentiles it is given to know this mystery. No wonder then, if they did gainsay: this was foretold from the first.
