God gave the Hebrew people the "Ten Commandments".
It had to go through Moses, because the people were too
scared to hear it directly from God, and they begged Moses
to go get it and bring it to them.
Now, if you want to say "So then it was really Moses", then
I have to ask you: Do you feel like it was really the mailman
who gave you the birthday present from your grandmother
out of town ?
