Genesis 20:12

Abram and Nahor took wives for themselves. The name of Abram’s wife was Sarai; and the name of Nahor’s wife was Milcah, the daughter of Haran, the father of Milcah and the father of Iscah.

“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.”

And Abraham said of Sarah his wife, “She is my sister.” So Abimelech king of Gerar sent and took Sarah.

Then the men of the place asked about his wife. And he said, “She is my sister,” for he was afraid to say, “my wife,” thinking, “lest the men of the place kill me on account of Rebekah, for she is beautiful in appearance.”

“As for me, where could I get rid of my reproach? And as for you, you will be like one of the wicked fools in Israel. So now, please speak to the king, for he will not withhold me from you.”
