Genesis 42:32

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

30 The man [who is] the lord of the land, spoke roughly to us, and took us for spies of the country.

31 And we said to him, We [are] true [men]; we are no spies:

32 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.

33 And the man, the lord of the country, said to us, By this 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 depart:

34 And bring your youngest brother to me: then shall I know that ye [are] no spies, but [that] ye [are] true [men]: then will I deliver to you your brother, and ye shall traffick in the land.

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