The song Eliyahu Ha’Navi, Elijah the Prophet, is customarily sung on Motza’ay Shabbat because ultimately, Elijah will be the harbinger of the Messianic age. As the Messiah will not come on Shabbat, each Motza’ay Shabbat this song is sung as a prayer that the week to come will bring about the final redemption.

Eliyahu Ha’Navi, Eliyahu Ha’Tishbi, Eliyahu Ha’Giladi
Bim’hayrah Yavo Ay’laynu Im Mashiach Ben David.

Elijah the Prophet, Elijah the Tishbite, Elijah the Giladite
May he soon come to us, with the Messiah, the son of David.
