Sforno on Genesis 43:2/ספורנו על בראשית מ״ג:ב׳

1שובו שברו לנו, for he thought that their intent in wanting to take Binyamin with them was in order to lose him as they had lost Joseph. He had previously accused them of bereaving him (deliberately) when he had said (42,36) אותי שכלתם, “you have bereaved me,” (transitive active conjugation). He meant to deny that what they had told him at the time had been the truth.
