Genesis 12:14-18

And it came to pass, that, when Abram was come into Egypt, the Egyptians beheld the woman that she was very fair.

The princes also of Pharaoh saw her, and commended her before Pharaoh: and the woman was taken into Pharaoh’s house.

And 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.

And the LORD plagued Pharaoh and his house with great plagues because of Sarai Abram’s wife.

And 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?
