Gregory the Great, on Isa 30:20

“And the Lord will give you spare bread, and short water: and will not cause thy teacher to flee away from thee any more, and thy eyes shall see thy teacher.”

“He has seen us sinning and has borne with it. He who forbade us to sin before we did it does not stop waiting to pardon us even after we have sinned. The one we have rejected is calling us. We have turned away from him, but he has not turned away. Hence Isaiah said, "Your eyes shall see your teacher, and your ears shall hear the voice of a counselor behind you." A person is counseled to his face, so to speak, when he is created for righteousness and receives the precepts of rectitude. When he despises these precepts, it is as if he is turning his back to his Creator's face. But he still follows behind us and counsels us that we have despised him, but he still does not cease to call us. We turn our backs on his face, so to speak, when we reject his words, when we trample his commandments under foot; but he who sees that we reject him still calls out to us by his commandments and waits for us by his patience, stands behind us, and calls us back when we have turned away.”
