Genesis 43:1-5

Now the famine was still severe in the land. So when they had eaten all the grain they had brought from Egypt, their father said to them, “Go back and buy us a little more food.” But Judah said to him, “The man warned us solemnly, ‘You will not see my face again unless your brother is with you.’ If you will send our brother along with us, we will go down and buy food for you. But if you will not send him, we will not go down, because the man said to us, ‘You will not see my face again unless your brother is with you.’ ”
