'Sunset' in the Bible

but you must sacrifice it in the evening in the place where he chooses to locate his name, at sunset, the time of day you came out of Egypt.

When evening arrives he must wash himself with water and then at sunset he may reenter the camp.

You must by all means return to him at sunset the item he gave you as security so that he may sleep in his outer garment and bless you for it; it will be considered a just deed by the Lord your God.
