One altar, and the cross it points to

The Bronze Altar of Burnt Offering

Step through the gate of the tabernacle courtyard and the first thing that meets you is not the sanctuary, not the lampstand, not the ark of glory hidden in the innermost room. It is an altar. Squarely in the way, standing at the entrance, is the place of burnt offering, described in Exodus 27:1, built of acacia wood and overlaid with brass. Nothing gets past it. This was deliberate. The design of Israel's worship taught with its very floor plan. Before anyone could draw near to God, sacrifice stood between the worshiper and the holy place. The bronze altar announced a truth the whole tabernacle would keep repeating: the way to God runs through death and blood, through a substitute given in the sinner's place. It is a hard doorway, and yet it is the door of mercy.

“And thou shalt make an altar of shittim wood, five cubits long, and five cubits broad; the altar shall be foursquare: and the height thereof shall be three cubits.”Exodus 27:1

The altar in Scripture

Exodus 27:1 through 8 gives the plan of this altar in plain measurements. It was square, five cubits by five cubits, and three cubits high, made of acacia wood and overlaid with brass. Four horns rose from its four corners, worked as one piece with the altar itself. It carried a network grate of brass, rings, and staves so that it could be borne along on the journey, for Israel's worship traveled with a pilgrim people. Its location matters as much as its dimensions. Exodus 40:6 sets this altar directly before the door of the tabernacle of the tent of the meeting, in the open courtyard where the sun and wind reached it. Unlike the golden furniture kept within the veils, the bronze altar stood exposed at the threshold. Everyone who entered the court passed it first. It was the meeting point of the ordinary Israelite and the God who dwelt in the midst of the camp. Upon it the fire never went out. Leviticus 6:12 and 13 command that the fire on the altar be kept burning continually, never permitted to die. Morning and evening the burnt offering ascended, described in Exodus 29:38 through 42 as a continual offering throughout Israel's generations. The lamb of the morning and the lamb of the evening framed each day with sacrifice, so that the smoke of atonement was always rising over the camp. The horns of the altar carried their own weight of meaning. Blood was applied to them in the sin offerings of Leviticus 4, and a man fleeing for his life might lay hold of them as a plea for mercy, as Adonijah does in 1 Kings 1:50 and 51. The altar was where guilt was dealt with and where the desperate reached for refuge. Brass, a metal that endures fire, clothed the wood so the whole structure could bear the flame without being consumed. Every feature spoke of judgment borne and access opened.

What it comes to mean

The placement preaches before any word is spoken. God set the altar of sacrifice at the entrance, not the exit, because there is no approach to Him that bypasses the question of sin. The tabernacle was a graded ascent toward glory, and the first step upward was downward, a creature laying its hand upon the head of a dying animal and confessing that death was deserved. To reach the God who is light, a worshiper first met the God who takes sin with deadly seriousness. Brass, or bronze, carries a consistent association through the Scriptures with judgment that can withstand fire. The bronze altar was built to hold flame day after day, year after year, and not be reduced to ash. Here the fire of divine justice fell, yet it fell on the offering and not on the offerer. That is the whole logic of substitution rendered in wood and metal and smoke. The one who brought the animal walked away alive because something had died in his place. We should be honest that these sacrifices did not, in themselves, remove sin. Hebrews 10:4 states plainly that the blood of bulls and goats cannot take away sins. The bronze altar was a teaching altar, a repeated sign pointing beyond itself. Its very repetition, the endless morning and evening lambs, testified that the debt was never finally paid there. Each new day required a new offering because no offering in that courtyard could reach the conscience or close the account forever. Yet the altar was not a lie or an empty ritual. It was God's appointed way of drawing near in that age, a genuine means of grace that held real forgiveness in trust, waiting for a fuller payment. It trained a nation to think in terms of blood and mercy, of a life given for a life. It kept the door open by keeping the fire burning. And it fixed in Israel's imagination the shape of salvation, so that when the true sacrifice came, there would be eyes ready to recognize the pattern they had walked past every day.
