You shall also make for it a grating, a network of bronze, and on the net you shall make four bronze rings at its four corners.
As God intended in the tabernacle to manifest his presence among his people, so there they were to pay their devotions to him, not in the tabernacle itself (into that only the priests entered as God's domestic servants), but in the court before the tabernacle, where, as common subjects, they attended.
Commenting on Exodus 27:1-8
And thou shalt, make for it a grate of network of brass,.... Or "sieve", as in Amo 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...
a grate of network of brass--sunk latticework to support the fire. four brazen rings--by which the grating might be lifted and taken away as occasion required from the body of the altar.
