10 Now there was a famine in the land; so Abram went down to Egypt to sojourn there, for the famine was severe in the land. 11 It came about when he came near to Egypt, that he said to Sarai his wife, “See now, I know that you are a beautiful woman; 12 and when the Egyptians see you, they will say, `This is his wife’; and they will kill me, but they will let you live. 13 “Please say that you are my sister so that it may go well with me because of you, and that I may live on account of you.” 14 It came about when Abram came into Egypt, the Egyptians saw that the woman was very beautiful. 15 Pharaoh’s officials saw her and praised her to Pharaoh; and the woman was taken into Pharaoh’s house. 16 Therefore he treated Abram well for her sake; and gave him sheep and oxen and donkeys and male and female servants and female donkeys and camels.
17 But the LORD struck Pharaoh and his house with great plagues because of Sarai, Abram’s wife. 18 Then Pharaoh called Abram and said, “What is this you have done to me? Why did you not tell me that she was your wife? 19 “Why did you say, `She is my sister,’ so that I took her for my wife? Now then, here is your wife, take her and go.” 20 Pharaoh commanded his men concerning him; and they escorted him away, with his wife and all that belonged to him.
I think it is just plain human-nature to have a sense of self-preservation, but Abram forgot one critical thing. He had the promise of God almighty that He was going to make Abram into a great nation. He obviously forgot that as he was traveling to Egypt. God would have taken care of him, even in a foreign land. Instead, he made himself look like a fool in front of Pharaoh.
