Genesis 42:14-17

But Joseph said, “It’s just as I said, you’re spies. This is how I’ll test you. As Pharaoh lives, you’re not going to leave this place until your younger brother comes here. Send one of you to get your brother while the rest of you stay here in jail. We’ll see if you’re telling the truth or not. As Pharaoh lives, I say you’re spies.” Then he threw them into jail for three days.
