Even as Sara obeyed Abraham, calling him lord

[a mere housewife]

Just to add to Katherine's post that those verses in the KJV read:

15The princes also of Pharaoh saw her, and commended her before Pharaoh: and the woman was taken into Pharaoh's house.
16And he entreated Abram well for her sake: and he had sheep, and oxen, and he asses, and menservants, and maidservants, and she asses, and camels.
17And the LORD plagued Pharaoh and his house with great plagues because of Sarai Abram's wife.
18And Pharaoh called Abram and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife?
19Why saidst thou, She is my sister? so I might have taken her to me to wife: now therefore behold thy wife, take her, and go thy way.


Which seems clearer. Why is there this difference?

 

[TimV]

Point taken, Katherine!!

But still, it would be interesting to see a commentary that insisted she was sleeping with the king. I think a better parallel would be found in Ester, where she was put into the king's seraglio. Interpreting Scripture with Scripture, Sarah would have been guilty of adultery in the first case, and that was taken so seriously that it's (in my opinion) beyond belief that there was no mention of punishment involved on her part.
