Short answer: Exodus 27 covers the construction of the bronze altar for burnt offerings, the courtyard of the tabernacle with its linen hangings, and the command to bring pure olive oil for the lampstand. The chapter establishes the means by which Israel approaches God — through sacrifice, within the boundaries of His court, and sustained by the light of His presence.
Introduction
Exodus 27 is a foundational chapter in the book of Exodus, situated within the larger narrative of God's redemption of Israel from Egypt and His establishment of the covenant at Sinai. This study guide provides a thorough examination of the chapter's content, themes, and theological significance, drawing exclusively from the World English Bible (WEB) translation.
The Bronze Altar (27:1-8)
The altar of burnt offering is made of acacia wood overlaid with bronze, measuring five cubits square and three cubits high. Horns on its four corners are of one piece with the altar. All its utensils — pots, shovels, basins, forks, and firepans — are made of bronze. A grating of bronze network is placed halfway up, and rings with poles allow for transport. The altar is the place where sacrifices are offered, making atonement possible.
The Courtyard (27:9-19)
The tabernacle courtyard is a rectangle 100 cubits by 50 cubits, enclosed by fine linen hangings on bronze pillars with silver hooks and bands. The south and north sides each have twenty pillars, the west has ten, and the east has twenty with the entrance. The screen at the gate is embroidered with blue, purple, and scarlet yarn. All the pegs are bronze. The courtyard defines the sacred space where Israel's worship occurs.
The Oil for the Lamp (27:20-21)
God commands Israel to bring pure olive oil, beaten, for the light so that the lamp may burn continually. Aaron and his sons are to keep the lamp burning in the Tent of Meeting from evening to morning before Yahweh. This is a perpetual statute throughout their generations.
“You shall make the altar of acacia wood, five cubits long, and five cubits wide. The altar shall be square. Its height shall be three cubits. You shall make its horns on its four corners. Its horns shall be of one piece with it. You shall overlay it with bronze. You shall make its pots to take away its ashes; and its shovels, its basins, its meat hooks, and its fire pans. You shall make all its vessels of bronze. You shall make a grating for it of network of bronze. On the net you shall make four bronze rings in its four corners. You shall put it under the ledge around the altar beneath, that the net may reach halfway up the altar. You shall make poles for the altar, poles of acacia wood, and overlay them with bronze. Its poles shall be put into the rings, and the poles shall be on the two sides of the altar when carrying it. You shall make it hollow with planks. They shall make it as it has been shown you on the mountain.
Exodus 27:1-8 (World English Bible)
“You shall make the court of the tabernacle: for the south side southward there shall be hangings for the court of fine twined linen one hundred cubits long for one side. Its pillars shall be twenty, and their sockets twenty, of bronze. The hooks of the pillars and their fillets shall be of silver. Likewise for the length of the north side, there shall be hangings one hundred cubits long, and its pillars twenty, and their sockets twenty, of bronze; the hooks of the pillars, and their fillets, of silver. For the width of the court on the west side shall be hangings of fifty cubits; their pillars ten, and their sockets ten. The width of the court on the east side eastward shall be fifty cubits. The hangings for the one side of the gate shall be fifteen cubits; their pillars three, and their sockets three. For the other side shall be hangings of fifteen cubits; their pillars three, and their sockets three. For the gate of the court shall be a screen of twenty cubits, of blue, and purple, and scarlet, and fine twined linen, the work of the embroiderer; their pillars four, and their sockets four. All the pillars of the court around shall be filleted with silver; their hooks of silver, and their sockets of bronze. The length of the court shall be one hundred cubits, and the width fifty throughout, and the height five cubits, of fine twined linen, and their sockets of bronze. All the instruments of the tabernacle in all its service, and all its pins, and all the pins of the court, shall be of bronze.
Exodus 27:9-19 (World English Bible)
“You shall command the children of Israel, that they bring to you pure olive oil beaten for the light, to cause a lamp to burn continually. In the Tent of Meeting, outside the veil which is before the covenant, Aaron and his sons shall keep it in order from evening to morning before Yahweh: it shall be a statute forever throughout their generations on the behalf of the children of Israel.
Exodus 27:20-21 (World English Bible)
The bronze altar was the most used piece of furniture in the tabernacle. Every day, morning and evening, a lamb was offered on it. On feast days and special occasions, additional sacrifices multiplied its use. The altar's position at the entrance of the courtyard meant that every worshiper had to pass by it to approach God. This constant reminder of the need for sacrifice shaped Israel's understanding of sin and atonement. The smoke rising from the altar day and night was a visible sign that the people's relationship with God depended on continuous sacrifice.
The courtyard's dimensions and materials created a clear boundary between the sacred and the common. The white linen hangings on bronze pillars defined a space that was set apart for God. The single entrance on the east side, with its embroidered screen of blue, purple, and scarlet, controlled access. Only those who had been purified could enter. This careful demarcation of sacred space taught Israel that God's presence is not to be approached casually. The courtyard was a place of transition from the ordinary world to the holy presence of God.
The perpetual lamp fueled by pure olive oil is rich in symbolic meaning. The oil, beaten from olives, represents the best of what the land produced, offered to sustain the light in God's dwelling. The lamp burning from evening to morning ensured that the sanctuary was never in darkness. This perpetual light symbolized God's constant presence with His people even through the night. It also prefigures the church as a light in the darkness, sustained by the oil of the Holy Spirit, and points to the eternal light of God's presence in the new creation where there is no night.
Gospel connection
The bronze altar of sacrifice points directly to the cross. Just as every sacrifice was offered on the altar, Christ offered Himself once for all on the cross. The blood applied to the altar's horns prefigures the blood of Christ that atones for sin. The perpetual lamp, fueled by the people's oil, points to Christ, the light of the world, and to the Holy Spirit, who sustains the church's witness. The courtyard's linen hangings, defining sacred space, prefigure the church as God's temple.
Application
This chapter reminds us that approaching God requires sacrifice and atonement. The altar stood at the entrance, the first thing Israel encountered when entering the courtyard. Similarly, we approach God only through the sacrifice of Christ. The perpetual lamp calls us to maintain the light of witness and worship consistently, not sporadically. The courtyard's boundaries remind us that worship is ordered and reverent, not casual.

Frequently asked questions
Why was the altar made of bronze instead of gold?
The bronze altar stood in the courtyard, exposed to the elements and the soot of burnt offerings. Bronze was more practical for this purpose. The distinction between bronze (courtyard) and gold (tabernacle interior) also reflects degrees of holiness: the closer to God's presence, the more precious the material.
What was the significance of the altar's horns?
The horns were projections at each corner, made of one piece with the altar. They were the most sacred part of the altar; a person seeking refuge could cling to them (1 Kings 1:50). Blood was applied to the horns during purification rituals. They symbolized the altar's power to atone and protect.
Why did the lamp need to burn continually?
The perpetual light symbolized God's constant presence with His people. It was a reminder that God never sleeps nor slumbers and that His presence is always available. The oil provided by the people also symbolized their ongoing participation in maintaining worship.
