Genesis 20:12 Meaning and Commentary

Genesis 20:12

And yet indeed [she is] my sister
In the same sense as Lot was his brother; for she was sister to Lot, and both were the children of Haran, the brother of Abraham: she [is] the daughter of my father, but not the daughter of my mother;
she was the daughter of his father, being his granddaughter, grandchildren are sometimes called children, but not the daughter or granddaughter of Abraham's mother; Terah having had two wives, by the one he had Haran, the father of Sarah, and by the other Abraham. According to the Arabic writers F6, Abraham and Sarah were the immediate children of Terah, but by two mothers:

``the mother of Abraham (they say) died, whose name was Juna, and Terah married another wife, whose name was Lahazib, some say Tahuitha, who bore him Sarah, afterwards married to Abraham; hence Abraham said, she is my sister on my father's side, but not on my mother's side:''
and she became my wife;
as in those times it was judged lawful, and so it has been accounted lawful in many nations to marry sisters on the father's side, when those on the mother's were prohibited F7.

Genesis 20:12 In-Context

10 Abimelech also asked Abraham, "Why did you do this?"
11 Abraham replied, "I thought, 'There isn't any respect for God in this place at all. They will kill me because of my wife.'
12 Besides, she really is my sister. She's the daughter of my father, but not the daughter of my mother. And she became my wife.
13 "God had me wander away from my father's house. So I said to her, 'Here is how you can show your love to me. Everywhere we go, say about me, "He's my brother." ' "
14 Then Abimelech gave Abraham sheep and cattle and male and female slaves. He also returned his wife Sarah to him.
