The legislation in the Pentateuch assigned numerous duties to the Hebrew priests and Levites. Chief among them were maintaining and transporting the tabernacle (Num. 3–4) and performing the rituals and liturgies associated with Israelite worship in the sanctuary (Exod. 28–29). It is likely that some of these duties were determined by lot and discharged on a rotating basis (cf. 1 Chron. 23–24).
The central theme of the Mosaic tabernacle is the dwelling of God in the midst of Israel. The actualization of God’s dwelling is expressed in every aspect of the tabernacle, including its structure, materials, courts, sanctuaries, and furnishings including the altars, the lampstand, and the ark of the covenant.
