It follows, She heard not the voice, she received not correction. The Prophet now explains and defines what the pollution was of which he had spoken: for true religion begins with teachableness; when we submit to God and to his word, it is really to enter on the work of worshipping him aright. But when heavenly truth is despised, though men may toil much in outward rites, yet their impiety discovers itself by their contumacy, inasmuch as they suffer not themselves to be ruled by God’s authority. Hence the Prophet shows, that whatever the Jews thought of their purity at Jerusalem, it was nothing but filth and pollution. He says, that they were unteachable, because they did not hear the Prophets sent to them by God.
