Genesis 42:29-34

29When they reached their father Jacob in the land of Canaan, they told him all that had happened to them:

30“The man who is the lord of the country spoke harshly to us and accused us of spying on the country.

31But we told him, ‘We are honest and not spies.

32We were twelve brothers, sons of the same father. One is no longer living, and the youngest is now with our father in the land of Canaan.’

33The man who is the lord of the country said to us, ‘This is how I will know if you are honest: Leave one brother with me, take food to relieve the hunger of your households, and go.

34Bring back your youngest brother to me, and I will know that you are not spies but honest men. I will then give your brother back to you, and you can trade in the country.’”
