Genesis 42:32

29 So when they came to Jacob their father, in the land of Canaan, they gave him an account of all their experiences, saying,

30 The man who is the ruler of the country was rough with us and put us in prison, saying that we had come with a secret evil purpose.

31 And we said to him, We are true men, we have no evil designs;

32 We are twelve brothers, sons of our father; one is dead, and the youngest is now with our father in the land of Canaan.

33 And the ruler of the land said, In this way I may be certain that you are true men; let one of you be kept here with me, while you go and take grain for the needs of your families;

34 And come back to me with your youngest brother: then I will be certain that you are true men, and I will give your brother back to you and let you do trade in the land.

35 And when they took the grain out of their bags, it was seen that every man's parcel of money was in his bag; and when they and their father saw the money, they were full of fear.
