Genesis 43:1-8

1 The famine was severe in the land.
2 When they finished eating the grain they had brought from Egypt, Israel said to his sons, "Go back and buy us a little more food."
3 Judah said to him, "The man gave us a severe warning: 'You won't be allowed to see me again unless your brother is with you.'
4 If you let our brother go with us, we'll go and buy food for you.
5 If you won't let him go, we won't go. The man said to us, 'You won't be allowed to see me again unless your brother is with you.'"
6 Israel asked, "Why have you made trouble for me by telling the man you had another brother?"
7 They answered, "The man kept asking about us and our family: 'Is your father still alive? Do you have another brother?' We simply answered his questions. How could we possibly know he would say, 'Bring your brother here'?"
8 Then Judah said to his father Israel, "Send the boy along with me. Let's get going so that we won't starve to death.
