Genesis 42:21-23
42:21 They said to one other, “Surely we’re being punished because of our brother, because we saw how distressed he was when he cried to us for mercy, but we refused to listen. That is why this distress has come on us!”
42:22 Reuben said to them, “Didn’t I say to you, ‘Don’t sin against the boy,’ but you wouldn’t listen? So now we must pay for shedding his blood!”
42:23 (Now they did not know that Joseph could understand them, for he was speaking through an interpreter.)
