3 Also you shall make its pans to receive its ashes, and its shovels and its basins and its forks and its firepans; you shall make all its utensils of bronze. 4 You shall make a grate for it, a network of bronze; and on the network you shall make four bronze rings at its four corners. 5 You shall put it under the rim of the altar beneath, that the network may be midway up the altar. 6 And you shall make poles for the altar, poles of acacia wood, and overlay them with bronze. 7 The poles shall be put in the rings, and the poles shall be on the two sides of the altar to bear it.

Commentary on Exodus 27:1-8
(Read Exodus 27:1-8)
In the court before the tabernacle, where the people attended, was an altar, to which they must bring their sacrifices, and on which their priests must offer them to God. It was of wood overlaid with brass. A grate of brass was let into the hollow of the altar, about the middle of which the fire was kept, and the sacrifice burnt. It was made of net-work like a sieve, and hung hollow, that the ashes might fall through. This brazen altar was a type of Christ dying to make atonement for our sins. The wood had been consumed by the fire from heaven, if it had not been secured by the brass: nor could the human nature of Christ have borne the wrath of God, if it had not been supported by Divine power.
