Genesis 43:7, 29

And 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]’? ”

And he looked up and saw his brother Benjamin, his mother’s [only other] son, and said, “Is this your youngest brother, of whom you spoke to me?” And Joseph said, “God be gracious to you and show you favor, my son.”
