The Songs of the Sabbath Sacrifice are a group of liturgical songs to be used on each of the first thirteen Sabbaths of the year, dating by the solar calendar. The copies found at Qumran are not generally understood as sectarian in nature. That is, they do not appear to reflect practices particular to the Qumran community. Eight manuscripts of the work were found in Qumran Cave 4 (4Q400 through 4Q407), with a further copy in Cave 11 (11Q17). The manuscripts date to the late Hasmonean and Herodian periods, from the middle of the second century BCE to the middle of the first century CE. The Songs focus on the angels and their worship and service of God in the heavenly Temple / palace, depicting the celestial sanctuary as a living temple comprised of a vast array of angelic beings.
