Exodus 27:1-8 meaning

The LORD now gave instructions on fashioning the altar, the place for the burning of sacrifices (also called the "bronze altar" in many places including Exodus 38:30 and 39:30 and Ezekiel 9:2) and other items associated with it. The altar was to have the following characteristics:

It was to be made of acacia wood, like the ark and other tabernacle items.

It was to be five cubits long and five cubits wide; the altar shall be square, and its height shall be three cubits. Since a cubit is around 18 inches, the altar was probably 7.5 feet (around 2.25 meters) on each side, making it square. It was to be three cubits tall, making it about 4.5 feet (around 1.3 meters) tall.

They were to make its horns on its four corners (v. 2). This is the first of many references to the horns of the altar. An altar with horns was not unique to Israel in the Ancient Near East. Other peoples built their altars with horns to represent the power of their gods. Here, they represented the power of the one true God.

In addition, these horns were to be of one piece with it, meaning that the horns were not separate pieces that were appended to the altar but were part of an altar made as one solid piece.

Moreover, they were to overlay it with bronze. Bronze was a less precious metal than gold or silver, but sturdy and ornate.

After the horns, there were instructions on how to make the utensils associated with the altar.

The first utensils mentioned were its pails, which were to be used for removing its ashes created by the fuel burned to cook the sacrifices. Along with the pails, they were to make its shovels and its basins and its forks and its firepans. A firepan was apparently like a charcoal starter, to maintain or start the fire for the altar. There is an episode in Numbers 16 where it seems each Levite who worked on the altar had their own firepan that was used to hold coals, in that instance "two hundred and fifty firepans" (Numbers 16:17). Finally, all its utensils were to be constructed of bronze.

There was to be a grating of network of bronze. For the network (or net) that constituted the grating they needed to make four bronze rings at its four corners, presumably to make it easier to transport. This grating would create a super-sized outdoor grill upon which the sacrifices could be "barbecued."

They were to put it (the grating) beneath, under the ledge of the altar, so that the net will reach halfway up the altar. This means that the net was to be installed on a ledge that was halfway up the altar, making it about 2 feet above the ground. The "barbecue pit" would have a recessed grating.

There were also to be poles for the altar to make the altar easier to transport. They were to be made of acacia wood and overlaid with bronze. In order to carry the altar, the poles shall be inserted into the rings so that the poles shall be on the two sides of the altar when it is carried .

The altar was to be hollow with planks. This would make it lighter to carry.

All of this was to be done as it was shown to Moses in the mountain.

The LORD made it very clear to Moses how to construct the altar and its utensils while he was on Mount Sinai. This command is repeated throughout, emphasizing how important it was to build to His exact specifications without any modifications or additions.

The horns on the altar appear later in the Old Testament. They were to be sprinkled with the blood of a sacrificed bull as a person's sin offering (Leviticus 4:2 - 34). They were also a place where a person accused of a crime could go and seek asylum (1 Kings 1:50, for example).

The Suzerain (Ruler) God asked His vassals (Israel) to make an altar so that they could offer animal sacrifices to Him. God's primary intent was for the sacrifices to affect the hearts of the people and result in obedience to His covenant with them. God desired the people to walk in fellowship with Him through obeying His commands, and thereby keep His covenant. The sacrifice was a means to assure the people that they could restore fellowship with God (and one another) when they messed up.

That God primarily desired obedience from the heart is stated overtly in the episode of King Saul offering a sacrifice against God's commands in 1 Samuel 15:20-23. There the prophet Samuel states:

"Has the LORD as much delight in burnt offerings and sacrifices as in obeying the voice of the LORD?"
(1 Samuel 15:22)

Obeying God's commands would lead to the great benefit of the people. If they live in self-governance, loving their neighbors and seeking mutual benefit, their society will thrive and be blessed. The sacrifice was an ongoing means of restoration of fellowship.

The book of Hebrews summarizes this intended purpose of the animal sacrifice to cover the weakness of humans, and their tendency to sin. The sacrifice is a means to "deal gently with the ignorant and misguided" by a leader who also understands his own weakness. Thus there is an ongoing restoration of fellowship.

"For every high priest taken from among men is appointed on behalf of men in things pertaining to God, in order to offer both gifts and sacrifices for sins; he can deal gently with the ignorant and misguided, since he himself also is beset with weakness; and because of it he is obligated to offer sacrifices for sins, as for the people, so also for himself."
(Hebrews 5:1-3)

The animal sacrifice also looked ahead to a better High Priest and a perfect sacrifice - both housed in the person of Jesus Christ. Animal sacrifice was a symbolic act that foreshadowed the ultimate sacrifice offered by the blood of Jesus Christ (Heb. 13:10, Romans 3:24-26; Heb. 9:6-14; 1 Pe. 1:18-21).

Jesus offered Himself as the perfect sacrifice, once for all time as a payment for sin (Hebrews 9:11-12). Jesus' sacrifice covered the sins of the world, and nailed them to the cross with Him (Hebrews 2:17; Colossians 2:13-14). God asks New Testament believers to live their lives as a living sacrifice, pleasing to Him (Romans 12:1).

The New Testament presents Jesus not only as our perfect sacrifice, offered once for all, but also as our perpetual and abiding high priest, who intervenes for us even when we sin. This passage from Hebrews 7 shows the function Jesus performs, showing that the role of High Priest was also a foreshadowing of Jesus:

"For it was fitting for us to have such a high priest, holy, innocent, undefiled, separated from sinners and exalted above the heavens; who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because this He did once for all when He offered up Himself"
(Hebrews 7:26-27).
