Genesis 42:18-25

18And Joseph said to them the third day, This do, and live; for I fear God: 19If ye are honest men, let one of your brethren be bound in the house of your prison: go ye, carry grain for the famine of your houses: 20But bring your youngest brother to me; so shall your words be verified, and ye shall not die. And they did so.

21And they said one to another, We are verily guilty concerning our brother, in that we saw the anguish of his soul, when he besought us, and we would not hear; therefore is this distress come upon us. 22And Reuben answered them, saying, Did I not speak to you, saying, Do not sin against the young man; and ye would not hear? therefore, behold, also his blood is required. 23And they knew not that Joseph understood them ; for he spoke to them by an interpreter.1 24And he turned himself away from them, and wept; and returned to them again, and spoke with them, and took from them Simeon, and bound him before their eyes. 25Then Joseph commanded to fill their sacks with grain, and to restore every man’s money into his sack, and to give them provision for the way: and thus did he to them.
