Now another thing that they were confident about was their integrity. Never mind that they had once sold their brother into slavery and had lived with that lie for two decades. They were honest men in their own eyes, but who was guilty? When the steward of Joseph's house went after them, according to Joseph's orders, accusing them of having stolen Joseph's silver drinking cup, they were stunned at the suggestion. They were honest men in their own eyes, they were men of integrity. Now in Genesis 44: 7
Ten men promised this, to be slaves if it was found among them. It takes a great deal of self-confidence to offer to be sold into slavery if any one of a number of a group of people is found to have done something wrong. What a chance they took.
