Exodus 27:4-5

4, 5. A grate of network The design of this is not made very clear by the statements of these verses . The compass of the altar is commonly supposed to have been a projecting border or framework running around the outside, and affording a place for the officiating priest to stand, or pass around, when arranging the fire or the victims offered . Accordingly, this network grating has by some been explained as reaching from this border to the ground, and so being beneath it, (Hebrews, from below.) It would thus serve as a support for the border. Others have imagined that it extended horizontally beyond the border, and served to catch coals or any thing else which might fall from the altar. Others, however, have located the grate inside of the altar, so as to serve for a sieve through which ashes might fall, as through a fire grate, into a hollow place within the altar, from whence they were removed by means of the shovels. In this case the four brazen rings at the corners were for the purpose of easily lifting the grate out, or setting it in its place. There appears nothing by which to determine which of these views is correct. If the rings mentioned in Exodus 27:7 are identical with those upon the net, then the first view named above would be the most natural explanation. But as the staves to fit into those rings are mentioned as for the altar, while these were for the net, we are not justified in assuming that they were identical. But while the exact location and purpose of this grating are not certainly fixed, the general form and appearance of the altar probably resembled the preceding cut.
