Genesis 42:29-34

29And they came into the land of Canaan, to Jacob their father, and told him all that had befallen them, saying,

30The man, the lord of the land, spoke roughly to us, and treated us as spies of the land.

31And we said to him, We are honest; we are not spies:

32we are twelve brethren, sons of our father; one is not, and the youngest is this day with our father in the land of Canaan.

33And the man, the lord of the land, said to us, Hereby shall I know that ye are honest: leave one of your brethren with me, and take [for] the hunger of your households, and go,

34and bring your youngest brother to me, and I shall know that ye are not spies, but are honest. Your brother will I give up to you; and ye may trade in the land.
