Genesis 42:33-34

WEB(i) 33 The man, the lord of the land, said to us, ‘By this I will know that you are honest men: leave one of your brothers with me, and take grain for the famine of your houses, and go your way. 34 Bring your youngest brother to me. Then I will know that you are not spies, but that you are honest men. So I will deliver your brother to you, and you shall trade in the land.’”
