Genesis 15:17 states: ויהי השמש באה ועלטה היה
What I would like to know why השמש באה is often translated as: 'the sun set (the going away of the sun) or was going down' while באה or בא has the meaning of 'to come, to enter; to approach, to come near'. How is it that when the sun comes it goes down? Is this because it appears as if the sun is coming to us?
