Genesis 42:9–20

⁹And Joseph remembered the dreams which he dreamed of them, and said unto them, Ye are spies; to see the nakedness of the land ye are come. ¹⁰And they said unto him, Nay, my lord, but to buy food are thy servants come. ¹¹We are all one man’s sons; we are true men, thy servants are no spies. ¹²And he said unto them, Nay, but to see the nakedness of the land ye are come. ¹³And they said, We thy servants are twelve brethren, the sons of one man in the land of Canaan; and, behold, the youngest is this day with our father, and one is not. ¹⁴And Joseph said unto them, That is it that I spake unto you, saying, Ye are spies: ¹⁵hereby ye shall be proved: by the life of Pharaoh ye shall not go forth hence, except your youngest brother come hither. ¹⁶Send one of you, and let him fetch your brother, and ye shall be bound, that your words may be proved, whether there be truth in you: or else by the life of Pharaoh surely ye are spies. ¹⁷And he put them all together into ward three days.

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