Verse 11 to 15 of Joshua 10. 

As the Amorites retreated down the road from Beth-horon, the Lorddestroyed them with a terrible hailstorm from heaven that continued until they reached Azekah. The hail killed more of the enemy than the Israelites killed with the sword. On the day the Lord gave the Israelites victory over the Amorites, Joshua prayed to the Lordin front of all the people of Israel. He said,

“Let the sun stand still over Gibeon,

So the sun stood still and the moon stayed in place until the nation of Israel had defeated its enemies. Is this event not recorded in The Book of Jashar? The sun stayed in the middle of the sky, and it did not set as on a normal day. There has never been a day like this one before or since, when the Lord answered such a prayer. Surely the Lord fought for Israel that day! Then Joshua and the Israelite army returned to their camp at Gilgal.
