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.
