John Chrysostom

Then that you may not deem it strange that they believed not, he introduces the prophecy which saith "Hearing ye shall hear and not understand," more now than then: "and ye shall see and not perceive" more now than then. This is not spoken for the former sort, but for the unbelievers. How then? Was it contrary to the prophecy, that those believed? "Go," it says, "unto this people" that is, to the unbelieving people. He did not say this to insult them, but to remove the offence.
