Genesis 50:17-18

17‘This is what you should say to Joseph, “I’m begging you to forgive the crime and the sin your brothers committed against you. What they did to you was very evil.” ’ So now, please forgive our crime, because we are servants of your father’s God.” Joseph cried when he got their message.

18Then his brothers also came and immediately bowed down in front of him. “We are your slaves!” they said.
