Genesis 20:9

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. Abimelech's open stand in this matter, particularly in inquiring of Abraham the reason and the object of his behavior, was well taken, for the king had acted in good faith, a fact that cannot be alleged on Abraham's side.
