Genesis 12:16
16 and he did treat Abram well on account of her. Abram received sheep and cattle, male donkeys, male servants, female servants, female donkeys, and camels. 17 But the Lord struck Pharaoh and his household with severe diseases because of Sarai, Abram’s wife. 18 So Pharaoh summoned Abram and said, “What is this you have done to me? Why didn’t you tell me that she was your wife?
LXX Genesis 12:16
16 And for her sake they dealt well with Abram, and he had sheep and calves and donkeys, male and female slaves, mules and camels. 17 And God tried Pharao and his house with great and grievous trials because of Sara, Abram’s wife. 18 Now when Pharao had called Abram he said, “What is this you have done to me, that you did not tell me that she is your wife?
Notes and References
"... In contrast with Abram who never asks about Sarai’s welfare, God intervenes by subjecting Pharaoh’s household with unstated afflictions. Somehow, the Egyptian Pharaoh connects his problems with his taking Sarai as his wife and questions Abram about his deception. Again, Abram says nothing. Although he is ordered to leave Egypt and is escorted out by Pharaoh’s men, he certainly did do well for himself. What likely happened to Sarai is ignored, both by Abram and the narrator. Inasmuch as she was said to be barren, her being taken as Pharaoh’s wife is seemingly unimportant. No one will know. In an addition to the story, LXX-G reports that Lot was with them. Although this does smooth the transition to the next chapter, it begs the question of when Lot joined Abram in Egypt ..."
