I thought: Surely the fear of God is not in this place; and they will slay me for my wife's sake. And moreover she is indeed my sister, the daughter of my father, but not the daughter of my mother; and so she became my wife. And 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 show unto me; at every place whither we shall come, say of me: He is my brother.
To Abimelech in the wife-sister narrative of Genesis 20:11 - 23 (KJV)
Let there be no strife, I pray thee, between me and thee, and between my herdmen and thy herdmen; for we be brethren.Is not the whole land before thee? separate thyself, I pray thee, from me: if thou wilt take the left hand, then I will go to the right; or if thou depart to the right hand, then I will go to the left.Abraham
I have lift up mine hand unto the LORD, the most high God, the possessor of heaven and earth, That I will not take from a thread even to a shoelatchet, and that I will not take any thing that is thine, lest thou shouldest say, I have made Abram rich…Abraham
