Genesis 42:12-14

"And he said unto them, Nay, but to see the nakedness of the land ye are come. And they said, We thy servants are twelve brethren, the sons of one man in the land of Canaan; and, behold, the youngest is this day with our father, and one is not. And Joseph said unto them, That is it that I spake unto you, saying, Ye are spies."

This is a further elaboration of the impromptu trial, initiated by Joseph on the spot, and conducted in the presence of everyone. The brothers supported their testimony by giving further information about the family, including the fact of Benjamin's being at home with Jacob, and the cryptic reference to Joseph who, they said, "is not." Joseph announced the verdict: Guilty! No underling could have complained about Joseph's handling of the case. Under the rules of that ancient society, every accused was considered guilty until proved innocent, and the burden of proof was always upon the defendant.
