The sectarians labored at their tasks until evening, and then repeated the purification rites and partook of a communal meal similar to the one held at midday. The nights were used not only for rest, but for study, the judgment of members, and prayer.

Thus the sect members combined everyday matters with spiritual concerns during the week, until they came to the Sabbath, which was devoted entirely to the worship of God through study and prayer. Their observance of the Sabbath is characterized by great stringency, as they sought to preserve the sanctity of the day. The "Songs of Sabbath Sacrifice" scroll reflects the "service of the heart" that was customary among the sectarians. The scroll includes thirteen hymns sung by particular angels - one on each Sabbath; each hymn was repeated four times throughout the year, thus covering the fifty-two weeks of the year. These hymns, as their title attests, were undoubtedly viewed as substitutes for the sacrifices offered in the Temple in Jerusalem. It seems that the sectarians viewed their Sabbath songs as a reflection of the hymns of the angels in the celestial Temple.
