Isaiah not only wrote but preached in the Temple. He was not, however, talking of a religion of official cult, of endless sacrifices and priestly ceremonies, but of an ethical religion of the heart: he was reaching over the heads of the priests to the people. A strong talmudic tradition says that he was murdered in the reign of the idol-worshipping King Manasseh; but he was not welcome to the orthodox priesthood, the Temple establishment, either.
