Joseph's Favoritism in Egypt

Joseph had 11 brothers, but he was the youngest and could interpret dreams. He got close to Pharaoh by predicting a famine that would have killed all Israelites if Joseph hadn't been sold into slavery. And so when his brothers came to like look for food in Egypt, he was able to give it to them. There's this long dialogue in four or five chapters where they don't even know it's him. It's fascinating.
