Also interspersed in the story (chapters 25–31) are God’s detailed instructions to Moses for building and furnishing the Tabernacle, the clothing and ordination of priests, and other liturgical matters. According to this segment (evidently P in inspiration), an elaborate structure is to be set up in the desert, in the centre of the camp, taken apart, transported, and assembled again, like the simple “Tent of Meeting” outside the camp, where Moses received oracular revelations from God. Indeed, the two concepts seem to have fused and the Tabernacle is also called the Tent of Meeting. Its prime function is to serve as a sanctuary in which sacrifices and incense are offered on altars and bread presented on a table; it is also equipped with various other vessels and furnishings, including a wooden ark, or cabinet, to contain the two tablets of the Covenant—the famous ark of the Covenant. It is, moreover, to be the place of God’s occasional dwelling and meeting with the people. Scholars believe that the elaborate details and materials described stem from a later, Canaanite, period but that the essential concept of a tent of meeting goes back to an earlier desert time. An account of the execution of the instructions for the building of the Tabernacle is presented in chapters 35–40 (following the apostasy, tablet breaking, and Covenant-renewal episodes), which duplicates to the letter the instructions in chapters 25–31. After the Tabernacle is completed and consecrated, it is occupied by the “glory,” or presence, of YHWH, symbolized by a cloud resting upon it. It is on this note that the book of Exodus ends.

Offerings, sacrifices, and priestly worship

The first verse attributes these regulations to YHWH, who speaks to Moses from the Tent of Meeting, beginning with the rules for offerings by the individual layman. These include burnt, cereal, peace, sin, and guilt offerings, all described in precise details. The prescription for priestly offerings is about the same, with some slight differences in the order of actions, and is presented much more briefly. In chapters 8–10 the narrative that was interrupted at the end of Exodus is resumed, and the ordination of Aaron and his sons by Moses, before the people assembled at the door of the Tent of Meeting is described, as are various animal sacrifices by Aaron and his sons under Moses’ direction and the subsequent appearance of God’s “glory” to the people. Aaron’s two older sons are burned to death by fire issuing forth from God because they have offered “unholy fire.” This story apparently emphasizes the importance of adherence to the precise cultic details, as does also the account (at the end of the chapter) of Moses’ anger at Aaron’s two remaining sons for not eating the sin offering. These stories were apparently used by the priestly authors to buttress the authority of the Aaronic priesthood.

Purification laws

With chapter 11 begin the regulations on ritual cleanness and uncleanness, starting with animals and other living things fit and unfit to eat—the basis of the famous Jewish dietary laws. Then come the uncleanness and required purification of women after childbirth, skin diseases, healed lepers, infected houses, and genital discharges. Chapter 16, which belongs in the narrative flow immediately after chapter 10, describes the priestly actions on the Day of Atonement, the culmination of ritual cleansing in Israel. It is a chapter rich in details on Israelite ritual and bound up with the salient religious theme of atonement.
