Thematic Bible: Standing still for a whole day in the valley of ajalon

On the day the Lord gave the Amorites over to the Israelites, Joshua spoke to the Lord in the presence of Israel: "Sun, stand still over Gibeon, and moon, over the valley of Aijalon." And the sun stood still and the moon stopped, until the nation took vengeance on its enemies. Isn't this written in the Book of Jashar? So the sun stopped in the middle of the sky and delayed its setting almost a full day.
