Sforno on Genesis 44:10/ספורנו על בראשית מ״ד:י׳

1גם עתה כדבריכם כן הוא. Even though now, in this instance the argument you cite is logical, correct, but in this special circumstance, the goblet in question belonging to the king, a man who has treated you well by giving back all your money in your sacks, the fact is that האיש אש אתו ימצא הגביע הוא יהיה לי עבד, and not all of you. Even this individual will not be sentenced to death as would be required if we applied the law in all its strictness.

2ואתם תהיו נקיים. You will both be free from becoming slaves or any other form of punishment.
