According to Joshua 10:13, in which book was the sun standing still also written?

Answer: The Book of Jashar

Joshua 10:13 asks, "Is this not written in the Book of Jashar?" (KJV: "Jasher"); the sun delayed going down about a full day.

“So the sun stood still and the moon stopped until the nation took vengeance upon its enemies. Is this not written in the Book of Jashar? “So the sun stopped in the middle of the sky and delayed going down about a full day.””— Joshua 10:13 (BSB)
