[Guests add this blessing for their host. (Tur Orach Chaiyim20l)]:
"May it be Hashem's will that the host should not be embarrassed or ashamed in this World or the World to Come. May hebe successful with all that he owns, and may all that he owns grow and multiply and be close to the city. May the Satan have no power over anything he does, and may no sin or thoughts of sin go through his mind, now or ever."
