Thematic Bible: Standing still in ajalon

Joshua spoke to Jehovah the day when Jehovah delivered the Amorites to the children of Israel. He said in sight of Israel: Sun, stand still upon Gibeon; and Moon, stand still in the valley of Ajalon. The sun stood still, and the moon stood still, until the people had avenged themselves upon their enemies. Is this not written in the book of Jasher? So the sun stood still in the midst of heaven, and did not go down for a whole day.
