Genesis 42:34 (KJV)

And they came unto Jacob their father unto the land of Canaan, and told him all that befell unto them; saying,

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 it came to pass as they emptied their sacks, that, behold, every man's bundle of money was in his sack: and when both they and their father saw the bundles of money, they were afraid.

And Jacob their father said unto them, Me have ye bereaved of my children: Joseph is not, and Simeon is not, and ye will take Benjamin away: all these things are against me.

And Reuben spake unto his father, saying, Slay my two sons, if I bring him not to thee: deliver him into my hand, and I will bring him to thee again.

And he said, My son shall not go down with you; for his brother is dead, and he is left alone: if mischief befall him by the way in the which ye go, then shall ye bring down my gray hairs with sorrow to the grave.
