Then spoke Joshua to Yahweh in the day when Yahweh delivered up the Amorites before the children of Israel; and he said in the sight of Israel, Sun, stand you still on Gibeon; You, Moon, in the valley of Aijalon.
Yes indeed, we believe that the sun did not set for the course of a whole day, giving us a very, very long day, unlike any ever known before or since.  Now, of course, there are many arguments against receiving this view: (1) This event is unknown anywhere else in the literature of the whole world.  (2) It is not even mentioned anywhere else in the O.T. (3) The normal motions of the earth rotating on its axis causes "sunsets" apart from any motion whatever by the sun itself.  Therefore, for the day to have been lengthened as here indicated, some drastic change in the rotation of the earth on its axis would have been necessary.  Joshua, of course, knew nothing of that; he merely prayed to God, telling what he wanted, but God knew how to grant the prayer, altogether apart from Joshua's ignorance (and apart from our ignorance as well).
