You can even take that further as god saying it's ok to have other gods, just not before him. As long as he comes first...

What cracks me up (among many things), about this supposed creator of the universe and everything in it that is supposed to be 'the' one true god is that he needs humans to do his work. Sends Moses to convince Pharoah to let his people go. If I was Moses I would have asked hey didn't you create everything and are all powerful etc. Csan't you just essentially transport them out of there and put them where you want them???? Pretty ridiculous. And that's just one example. That's why I say it was Enlil. Just a simple fleshe and blood extra terrstrial playing god.
