"A cup is set out for Elijah during the seder meal"

 


Tradition of Elijah's cup during the seder meal (quoted from Chabad.org).

 

Cup of Elijah

"1) There is an open question in the Talmud whether we are obligated to have four or five cups on the night of Passover. Since the issue was never resolved, we pour a fifth cup, but do not drink it.

After heralding the coming of the Messiah, one of Elijah's tasks will be to resolve all hitherto unanswered halachic questions. Thus this fifth cup whose status is in doubt is dubbed "Elijah's Cup," in anticipation of the insight he will shed on the matter.

2) The four cups correspond to the four "expressions of redemption" promised by G‑d: "I will take you out from the suffering of Egypt, and I will deliver you from their bondage; I will redeem you with an outstretched arm and with great judgments. I will take you to Myself as a nation..."3 The fifth cup corresponds to the fifth expression of redemption which comes in the following verse: "I will bring you to the Land..." This expression, however, is an allusion to the future messianic redemption which will be announced by Elijah"

 

According to Jewish teaching, Elijah heralds the coming of the Messiah!
