Genesis 40:15

for indeed I was stolen away out of the land of the Hebrews; and here also have I done nothing that they should put me into the dungeon. Joseph's plea may well be understood, when he asks the butler to keep him in favorable memory. He explains that he did not flee from his home country on account of some crime, but that he had been abducted by force. The expression shields his brothers, so far as their share in his present plight was concerned, and is altogether consistent, for Joseph undoubtedly informed the Ishmaelites that bought him of his station. He speaks with the same caution in referring to his imprisonment, merely stating that he was guilty of no crime which would have merited his being placed into this pit.
