Abram and Nahor both got married. Abram's wife was named Sarai, and Nahor's wife was named Milcah. (She was the daughter of Haran, who was the father of both Milcah and Iscah).
Since my God made me move far away from my family home, I told her, ‘If you really love me, then wherever you go with me you must tell people: He's my brother.’”
During his time there, when Abraham told people about his wife Sarah, he said, “She's my sister.” So Abimelech, king of Gerar, sent for Sarah and took her to become one of his wives.
When the men there asked him about his wife, he told them, “She's my sister,” because he was afraid. He said to himself, “If I say she's my wife, the men here will kill me to get Rebekah, because she's so beautiful.”
Stop and think about me! How could I bear such a disgrace? Think about yourself too! You'd be treated with contempt, regarded as a complete fool in Israel! Please talk with the king, for he won't stop you marrying me.”
