The idea of a messianic age, an era of global peace and knowledge of the Creator, has a prominent place in Jewish thought, and is incorporated as part of the end of days. A well-known passage from the Book of Isaiah describes this future condition of the world: "They shall beat their swords into plowshares and their spears into pruning hooks; nation will not lift sword against nation and they will no longer study warfare" (2:4). Maimonides (1135–1204) further describes the Messianic Era in the Mishneh Torah: "And at that time there will be no hunger or war, no jealousy or rivalry. For the good will be plentiful, and all delicacies available as dust. The entire occupation of the world will be only to know God;... the people Israel will be of great wisdom; they will perceive the esoteric truths and comprehend their Creator's wisdom as is the capacity of man. As it is written (Isaiah 11:9): 'For the earth shall be filled with the knowledge of God, as the waters cover the sea.'"
