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 And Abimelech said to Abraam, What hast thou seen in that thou hast done this?

11 And Abraam said, Why I said, Surely there is not the worship of God in this place, and they will slay me because of my wife.

12 For truly she is my sister by my father, but not by my mother, and she became my wife.

13 And it came to pass when God brought me forth out of the house of my father, that I said to her, This righteousness thou shalt perform to me, in every place into which we may enter, say of me, He is my brother.

14 And Abimelech took a thousand pieces of silver, and sheep, and calves, and servants, and maid-servants, and gave them to Abraam, and he returned him Sarrha his wife.
