'Moon' in the Bible

Then Joshua spoke 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 still on Gibeon! You, moon, stop in the valley of Aijalon!"

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.
