Genesis 43:6-7

6And Israel (Jacob) said, “Why did you treat me so badly by telling the man that you had another brother?”

7And they said, “The man asked us straightforward questions about ourselves and our relatives. He said, ‘Is your father still alive? Have you another brother?’ And we answered him accordingly. How could we possibly know that he would say, ‘Bring your brother down [here to Egypt]’? ”
