Genesis 42:29-34

29When the brothers came to their father, Jacob, in the land of Canaan, they told him everything that had happened to them.

30“The man who is governor of the land spoke very harshly to us,” they told him. “He accused us of being spies scouting the land.

31But we said, ‘We are honest men, not spies.

32We are twelve brothers, sons of one father. One brother is no longer with us, and the youngest is at home with our father in the land of Canaan.’

33“Then the man who is governor of the land told us, ‘This is how I will find out if you are honest men. Leave one of your brothers here with me, and take grain for your starving families and go on home.

34But you must bring your youngest brother back to me. Then I will know you are honest men and not spies. Then I will give you back your brother, and you may trade freely in the land.’”
