Genesis 42:25-34

Then Joseph commanded to fill their vessels with grain, and to restore every man’s money into his sack, and to give them provision for the way: and thus was it done unto them. And they laded their asses with their grain, and departed thence. And as one of them opened his sack to give his ass provender in the lodging-place, he espied his money; and, behold, it was in the mouth of his sack. And he said unto his brethren, My money is restored; and, lo, it is even in my sack: and their heart failed them, and they turned trembling one to another, saying, What is this that God hath done unto us? And they came unto Jacob their father unto the land of Canaan, and told him all that had befallen them, saying, The man, the lord of the land, spake roughly with us, and took us for spies of the country. And we said unto him, We are true men; we are no spies: we are twelve brethren, sons of our father; one is not, and the youngest is this day with our father in the land of Canaan. And the man, the lord of the land, said unto us, Hereby shall I know that ye are true men: leave one of your brethren with me, and take grain for the famine of your houses, and go your way; and bring your youngest brother unto me: then shall I know that ye are no spies, but that ye are true men: so will I deliver you your brother, and ye shall traffic in the land.
