'Sun' in the Bible

From the wilderness, and this Lebanon, even to the great river, the river Euphrates, all the land of the Hittites, and to the great sea toward the going down of the sun, shall be your border.

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.

It happened at the time of the going down of the sun, that Joshua commanded, and they took them down off the trees, and cast them into the cave in which they had hidden themselves, and laid great stones on the mouth of the cave, which remain to this very day.

Behold, I have allotted to you these nations that remain, to be an inheritance for your tribes, from the Jordan, with all the nations that I have cut off, even to the great sea toward the going down of the sun.
