Prophetic Holiness and Ethics
Devarim Rabba places Isaiah alongside Moses as the greatest of the prophets (2:4). Isaiah has a central standing among the prophets of Israel and it is noteworthy that the most common epithet for God that Isaiah uses is K’dosh Yisrael “The Holy One of Israel” (Is 1:4). According to Isaiah and most of the other classical prophets, holiness is articulated in terms of social justice and political ethics.
