Unlike Amos and Micah, Isaiah was not only the prophet of denunciation but also the prophet of hope.
In addition to these complete commentaries, we have fragments of some others (of that on Isaiah, for example), principally met with in catenae.
Even more insistently does Isaiah present the great truth of God's universal sovereignty.
Chap. vi., which describes a vision of Isaiah "in the death-year of King Uzziah" (740 or 734 B.C.?) may possibly have arisen out of notes put down in the reign of Jotham; but for several reasons it is not an acceptable view that, in its present form, this striking chapter is earlier than the reign of Ahaz.
This involved an entire reconstruction of theological ideas which went beyond even the reconstructions of Amos and Isaiah.
