The Book of Jasher is an ancient Hebrew text that presents itself as an additional historical account of events found in the Old Testament of the Bible. The book covers a wide range of topics, from the creation of the world to the conquest of Canaan, and includes stories not found in the Bible. These stories include a detailed account of the battle between the prophet Abraham and a group of kings, the story of the sun standing still during Joshua's battle, and the backstory of Caleb, one of the Israelite spies. Although its authenticity and authorship remain uncertain, "The Book of Jasher" has been widely read and studied by scholars and laypeople alike, and has been referenced in a variety of works of literature and media over the years.
