Genesis 42:21-23

21Then they said to one another, “Surely we are being punished because of our brother. We saw his anguish when he pleaded with us, but we would not listen. That is why this distress has come upon us.”

22And Reuben responded, “Didn’t I tell you not to sin against the boy? But you would not listen. Now we must account for his blood!”

23They did not realize that Joseph understood them, since there was an interpreter between them.
