Genesis 39:22

And the keeper of the prison put Joseph in charge of all the prisoners who were in the prison . Whatever was done there , he was the one who did it.

So the warden put Joseph in charge of all those held in the prison, and he was made responsible for all that was done there.

And the keeper of the prison committed to Joseph's hand all the prisoners that were in the prison; and whatsoever they did there, he was the doer of it .
