Genesis 42:29 (KJV)

And he turned himself about from them, and wept; and returned to them again, and communed with them, and took from them Simeon, and bound him before their eyes.

Then Joseph commanded to fill their sacks with corn, and to restore every man's money into his sack, and to give them provision for the way: and thus did he unto them.

And they laded their asses with the corn, and departed thence.

And as one of them opened his sack to give his ass provender in the inn, he espied his money; for, behold, it was in his sack's mouth.

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 were afraid, saying one to another, What is this that God hath done unto us?

The man, who is the lord of the land, spake roughly to us, and took us for spies of the country.

And we said unto him, We are true men; we are no spies:

We be 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 country, said unto us, Hereby shall I know that ye are true men; leave one of your brethren here with me, and take food for the famine of your households, and be gone:

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 traffick in the land.
