Genesis 20:10

⁸  Therefore Abimelech rose early in the morning, and called all his servants, and told all these things in their ears: and the men were sore afraid.

⁹  Then Abimelech called Abraham, and said unto him, What hast thou done unto us? and what have I offended thee, that thou hast brought on me and on my kingdom a great sin? thou hast done deeds unto me that ought not to be done.

¹⁰  And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing?

¹¹  And Abraham said, Because I thought, Surely the fear of God is not in this place; and they will slay me for my wife's sake.

¹²  And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.
