Genesis 42:21-24

And they said one to another, We are verily guilty concerning our brother, in that we saw the distress of his soul, when he besought us, and we would not hear; therefore is this distress come upon us. And Reuben answered them, saying, Spake I not unto you, saying, Do not sin against the child; and ye would not hear? therefore also, behold, his blood is required. And they knew not that Joseph understood them; for there was an interpreter between them. And he turned himself about from them, and wept; and he returned to them, and spake to them, and took Simeon from among them, and bound him before their eyes.
