Dead Sea Scrolls:
From The Community Rule:
When these become members of the Community in Israel according to all these rules, they shall establish the spirit of holiness according to everlasting truth. They shall atone for guilty rebellion and for sins of unfaithfulness, that they may obtain loving-kindness for the Land without the flesh of holocausts and the fat of sacrifice. And prayer rightly offered shall be as an acceptable fragrance of righteousness, and perfection of way as a delectable free-will offering. At that time, the men of the Community shall set apart a House of Holiness in order that it may be united to the most holy things and a House of Community for Israel, for those who walk in perfection.
