(4) A grate of network.--Rather, a grating of network. The position of the grating is doubtful. According to one view, it reached from the middle of the altar to its base, and protected the sides of the altar from the feet of the ministering priests. According to another, it surrounded the upper part of the altar, and was intended to catch any portions of the victims that accidentally fell off. There are no sufficient data to enable us to determine between these views.

Upon the net shalt thou make four brasen rings.--The brazen altar, like the ark and the table of shewbread, was to be carried by the priests when the Israelites changed their camping-ground. It therefore required "rings," like them (Exodus 25:12; Exodus 25:26). These were, in the case of the altar, to be attached to the network, which must have been of a very solid and substantial character.

Verse 4. - Thou shalt make for it a grate. Rather, "a grating." This was probably a protection for the lower part of the altar, and prevented it from being touched by the feet of the ministrant priests. It was outside the altar, and had the rings attached to it, by which the altar was carried when the Israelites journeyed.

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.And thou shalt, make for it a grate of network of brass,.... Or "sieve", as in Amos 9:9, it was a plate of brass with holes in it, to let through either the blood that drained from the parts of the sacrifice, or the ashes of it; for this was the focus or hearth, on which the sacrifice and the wood were laid and burnt: this, according to the Targum of Jonathan on Exodus 38:4 was to receive the coals and bones which fell from the altar: and so may denote the purity of Christ's sacrifice, which was offered up without spot to God, and the use of him as the altar to sanctify our gifts, and take away the sins of our holy things:

and upon the net shalt thou make four brazen rings in the four corners thereof; by which, with chains put into them, the grate was fastened to the four horns of the altar, and the use of them was to let it down and hang in the middle of the altar, and to take it up when there was occasion for it; though some think these rings were not "in" the grate, but "by" it, as the particle may be rendered, a little lower than that, on the sides of the altar; into which the staves after mentioned were put, and with which the altar was carried when removed from place to place.
