10And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing? 11And 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. 12And 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. 13And it came to pass, when God caused me to wander from my father’s house, that I said unto her, This is thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He is my brother. 14And Abimelech took sheep, and oxen, and menservants, and womenservants, and gave them unto Abraham, and restored him Sarah his wife.
