It seemed that Abram had made a good choice—at least from his point of view. Because his “sister” was part of Pharoah’s harem, everyone wanted to make deals with him. Abram was living a charmed life; he got rich. Sheep, cattle, donkeys, camels, manservants, and maidservants, all added to his wealth. His status and power grew.

But he had forgotten about God. And he had put Sarai in a very compromising position. She felt used and abandoned, but her husband and by God.

But God had not forgotten about her. He brought a serious sickness to Pharoah’s household.

Because of her, Abram got along very well: he accumulated sheep and cattle, male and female donkeys, men and women servants, and camels. But God hit Pharaoh hard because of Abram’s wife Sarai; everybody in the palace got seriously sick.
