Exodus 27

Exodus 27 details the instructions for constructing the brazen altar for sacrifice, the external court of the tabernacle, and the provision for the lamp's oil, establishing the precise physical framework for the community to approach God. The passage moves from the point of sacrifice to the perimeter of the holy space, and finally to the perpetual maintenance of light within the tent.

• Verses 1-8 describe the construction of the altar, specifically noting its dimensions, materials, and portability.
• Verses 9-19 detail the dimensions and materials for the court curtains, pillars, and gate, setting the boundaries of the tabernacle complex.
• Verses 20-21 command the Israelites to provide pure oil for the lamps and assign the priests the duty of tending them from evening to morning.

• The altar of shittim wood (שִׁטָּה, H7848) overlaid with bronze (נְחֹשֶׁת, H5178), measuring 5x5x3 cubits (אַמָּה, H520).
• The court dimensions of 100 cubits (אֹרֶךְ, H753) by 50 cubits (רֹחַב, H7341).
• The repeated use of bronze (נְחֹשֶׁת, H5178) for the outer courtyard elements, in contrast to the gold used within the sanctuary.
• The command for the lamp to burn 'always' (v. 20) under the care of Aaron and his sons.

This chapter defines the boundary between the common and the holy, establishing that access to God requires both blood sacrifice at the altar and the maintenance of light provided by the Lord's chosen mediators.

God prescribes the exact conditions for public worship, emphasizing that human approach to His presence is mediated through sacrifice and sustained by His appointed light.

The text systematically moves from the most essential item of worship—the altar of sacrifice—outward to the parameters of the enclosure, ending with the required maintenance of the light.

• The designation of the lamp-tending duty as a 'statute for ever unto their generations' (v. 21).

• Make an altar of shittim wood (v. 1).
• Bring pure oil olive beaten for the light (v. 20).
• Aaron and his sons shall order it from evening to morning (v. 21).

• The Israelites are in the wilderness of Sinai, receiving instructions for the structure that will serve as the mobile center of Yahweh's presence among His people.

• The use of shittim wood (acacia) reflects the local environment of the wilderness, chosen for its durability in desert climates.
• The standard of measurements (cubits, אַמָּה, H520) utilizes the length of the forearm, a common ancient near eastern unit.

• This chapter follows the instructions for the interior furniture of the tabernacle (Ark, Table, Lampstand) and focuses on the exterior elements of the courtyard.

• This passage establishes the architectural pattern for the Tabernacle which is later replicated in the Temple of Solomon.
• New Testament authors view this sacrificial system as a shadow of the work of Christ (e.g., Hebrews 13:10), who is the true altar and mediator.

• Exodus 27:21 relates to Leviticus 6:12-13, which mandates the fire on the altar be kept burning perpetually.

• shittim wood (שִׁטָּה, H7848) refers to the acacia tree; the name implies thorns.
• altar (מִזְבֵּחַ, H4196) literally means a place of slaughter/sacrifice.
• The word for 'hollow' (נָבַב, H5014) regarding the altar suggests the frame was built to be filled with earth for the actual burning area.

• The altar is explicitly called 'hollow' (v. 8), which aligns with the subsequent instruction in Exodus 20:24 that altars should be made of earth; the wooden frame served as the structure for the earth and bronze.
• The text specifies the lamp must be tended 'before the Lord' (v. 21), emphasizing that the priestly work is always in the divine presence.

• Matthew Henry observes that the brazen altar represents Christ dying for atonement; he notes that while the wood might have burned, the bronze overlay protected it—symbolizing Christ's human nature sustained by divine power through the wrath of God. Debate exists in historical theology: some traditions, emphasizing the typology of the Temple, view the altar as a literal future millennial structure, while others view it as a finished type fulfilled solely in the crucifixion of Christ. This text provides the structural blueprint without explicitly defining the eschatological horizon.
