Genesis 42:33-34

VIN(i) 33 "The governor of that land said to us, 'This is how I will know that you are honest men: Leave one of your brothers with me. Take food for your starving families and go. 34 And bring your youngest brother to me. Then I will know that you are not spies but you are honest. And I will give your brother back to you, and you will trade in the land.'"
