The Book of Isaiah was written between the 8th-6th centuries BC and attributed to three authors: Isaiah son of Amoz who prophesied in the 8th century; an exile disciple called Second Isaiah; and a post-exilic writer called Third Isaiah. Isaiah forms the idea that Jerusalem has a future with God as a city of justice and peace. The book contains prophecies, indictments of Israel/Judah for failing to create a just society, and hope for those disillusioned by the lack of progress. It conveys that a society of peace is possible when people cooperate with God's plans for justice.
