Genesis 42:33

33Then the man, the lord of the land, said to us, a‘By this I shall know that you are honest men: leave one of your brothers with me, and take bgrain for the famine of your households, and go your way.

Genesis 43:5-7

5But if you will not send him, we will not go down, for the man said to us, ‘You shall not see my face, unless your brother is with you.’” 6Israel said, “Why did you treat me so badly as to tell the man that you had another brother?” 7They replied, “The man questioned us carefully about ourselves and our kindred, saying, ‘Is your father still alive? Do you have another brother?’ What we told him was in answer to these questions. Could we in any way know that he would say, ‘Bring your brother down’?”
