The Implications of Pharaoh Sleeping With Sarah

I typically start consuming calories at 9pm and I'm done before bedtime. If you do the one meal a day diet what time do you eat, or would you suggest eating your one meal. And this scenario where Abraham and Sarah are interacting with Pharaoh is a microcosm of what later happens with Moses and Pharaoh. There may also be a significance here about plundering the Egyptians because Abraham gets rewarded by Pharaoh even though he goes down to Egypt as a wandering traveler he comes back richer than he left. So that's also what's going on here on a literary level in the text.
