Shalom Aleichem (Hebrew: שָׁלוֹם עֲלֵיכֶם, 'Peace be upon you') is a traditional song sung by many Jews every Friday night upon returning home from synagogue prayer. It signals the arrival of the Shabbat, welcoming the angels who accompany a person home on the eve of the Shabbat. The custom of singing "Shalom Aleichem" on Friday night before Eshet Ḥayil and Kiddush is now nearly universal among religious Jews.
There are many tunes to the song and each stanza is recited 3 times[1]
