More information: An empty chair is often left at the Passover Seder table for Prophet Elijah. This empty seat is traditionally at the head of the table. In addition to this seat, a cup of wine is placed untouched at the table for Elijah. Based on the teachings of Judaism, it is believed that someday, Prophet Elijah will take his sit on that empty chair and announce the arrival of King Messiah (also known as Moshiach in Hebrew).
