It is also a tradition to invite guests to the seder. Many people will invite travelers, neighbors, and friends, both Jewish and not Jewish. The idea at Passover is to be hospitable and inclusive, to the best of a household’s ability. There is a tradition of leaving an empty place setting and chair at the table for the biblical prophet Elijah, who in Jewish legend will herald the coming of the messiah. This seat is often seen as a way of leaving one chair for a last minute invite, but some families leave the chair empty.
