The sun stood still, and the moon stayed, Until the nation had avenged themselves of their enemies. Isn't this written in the book of Jashar? The sun stayed in the midst of the sky, and didn't hurry to go down about a whole day.
2.    This may have been a local miracle whereby God provided additional light for Israel. Some advocates of this view believe God created unusual atmospheric conditions that resulted in the refraction of sunlight after the sun had set. Others feel God provided a light for Israel that may even have looked like the sun but was a different source of light, such as the shekinah. [Note: Bush, p. 119; Davis and Whitcomb, pp. 69-70; Keil and Delitzsch, pp. 109-112; et al.] The main problem with this view is the language used in the text that seems to imply an actual alteration of the earth’s rotation. Advocates reply that this is the language of appearance and point to similar miracles in Scripture (e.g., Exodus 10:21-23; 2 Kings 20:10-11). Some also cite God’s promise to provide day and night regularly, which seems to favor this view (Genesis 8:22; cf. Jeremiah 33:20-21).
