Genesis 42:21-22

21Then they said to one another, “We are truly guilty concerning our brother, for we saw the anguish of his soul when he pleaded with us, and we would not hear; therefore this distress has come upon us.”

22And Reuben answered them, saying, “Did I not speak to you, saying, ‘Do not sin against the boy’; and you would not listen? Therefore behold, his blood is now required of us.”
