Genesis 42:34 And bring your youngest brother unto me: then shall I know that ye are no spies, but that ye are true men: so will I deliver you your brother, and ye shall traffick in the land.

Genesis 43:5 But if thou wilt not send him, we will not go down: for the man said unto us, Ye shall not see my face, except your brother be with you.

Genesis 44:23 And thou saidst unto thy servants, Except your youngest brother come down with you, ye shall see my face no more.
