MIZMOR SHIR LE-YOM HA-SHABBAT (Heb. לְיוֹם הַשּׁבָּת מִזְמוֹר שִׁיר; "A Psalm, a Song for the Sabbath Day"), the superscription of Psalm 92 which, according to the Talmud (Tam. 7:4, RH 31a, Sof. 18:1) was the Sabbath hymn chanted by the levites in the Temple. The Psalm forms part of the Sabbath eve service in which the Sabbath (*Kabbalat Shabbat) is welcomed. It is also part of the *Pesukei de-Zimra and the daily hymn at the conclusion of the Sabbath morning service, as well as in the Sabbath Minḥah service in the Sephardi and some Ashkenazi rites. Some aggadic sources ascribe its authorship to Adam who pronounced it in his great joy for the gift of repentance. In the course of time, it was forgotten until Moses reintroduced it with ten other psalms (Gen. R. 22, end; Mid. Ps. 90:30).
