The Problem
On the day the Lord gave the Amorites
over to Israel, Joshua said to the Lord in
the presence of Israel: “Sun, stand still
over Gibeon, and you, moon, over the
Valley of Aijalon.” So the sun stood still,
and the moon stopped, till the nation
avenged itself on its enemies, as it is
written in the Book of Jashar.
Joshua 10:12-13
