Contradiction with John 8:44
This verse describes the devil as a liar and the father of lies, opposing the brothers' claim of innocence in Genesis 44:7.
John 8:44: Ye are of [your] father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it. [of his own: or, from his own will or disposition]
