"Leupold’s commentary begins with a nearly fifty page introduction covering topics as diverse as the historical situation at the time of Isaiah, biographical information on the prophet, a discussion of the current thoughts on authorship, Isaiah’s theology, and Isaiah’s prophecies in the light of the Dead Sea Scrolls. It is in the area of illuminating the Messianic prophecies and revealing the import of the historical passages and background that this exposition excels." - logos online.
