'Sunset' in the Bible

Are they not across the Jordan, west of the way toward the sunset, in the land of the Canaanites who live in the Arabah, opposite Gilgal, beside the oaks of Moreh?

but at the place where the Lord your God chooses to establish His name, you shall sacrifice the Passover in the evening at sunset, at the time that you came out of Egypt.

As evening approaches, he must wash himself with water. Then at sunset, he may return to the camp.

Be sure to return it to him at sunset. Then he will sleep in it and bless you, and this will be counted as righteousness to you before the Lord your God.
