John Gill Commentary Genesis 44:10

"And he said, Now also let it be according unto your words: he with whom it is found shall be my bondman; and ye shall be blameless." — Genesis 44:10 (ASV)

And he said, now also [let] it [be] according to your
words
Not according to the full extent of their words, but according to a part of them; that he only should be a servant that was found guilty; so moderating the punishment which they had fixed, and were willing to submit to, and therefore could not object to what he next proposes: he with whom it is found shall be my servant ;
speaking in the name of Joseph, whom he represented, and who had directed him what to say: and you shall be blameless ;
acquitted of the charge, and pronounced innocent, and let go free.
