Wednesday: Define face to face

From Exodus 33-35:

1. Define face to face - We see in Exodus 33 that God spoke to Moses face to face. However, later he asks to see God's glory, and God says his face must not be seen. I wonder how this could be true? Was it God the Father versus God the Son, or was it like he spoke face to face, but not really literally face to face?

2. In Exodus 33:11, we see that although Moses would go back into the camp after meeting with God in the tent of meeting, Joshua (Moses' aide) would stay behind in the tent of meeting. He must've really been amazed by seeing God's power there.

3. Exodus 34:13 "...for the Lord, whose name is Jealous, is a jealous God." Isn't this redundant? Why would this be stated this way? For emphasis?

4. Moses had a radiant face. Now that is something. I wonder what it looked like.

5. Many of the commands that God provided actually make a whole lot of sense looking back, many for sanitary reasons or other things like that. The Sabbath was to be holy, but it is interesting that God specifically says that they are not to light a fire on the Sabbath day. Does this mean as long as one is already going, you can keep it going, but cannot light it, or does it mean not to have a fire burning on the Sabbath? I assume the first option. If that is the case, I wonder about it, since it is actually almost as easy to start the fire as it is to keep feeding the fire all night just to keep it going for the next day.
