SEV Biblia, Chapter 27:4
Y le harás un enrejado de bronce de hechura de red; y sobre la red harás cuatro anillos de bronce a sus cuatro esquinas.
Clarke's Bible Commentary - Exodus 27:4
Verse 4. Thou shalt make for it a grate] Calmet supposes this altar to have been a sort of box, covered with brass plates, on the top of which was a grating to supply the fire with air, and permit the ashes to fall through into the siroth or pan that was placed below. At the four corners of the grating were four rings and four chains, by which it was attached to the four horns; and at the sides were rings for the poles of shittim wood with which it was carried. Even on this there is a great variety of opinions.
Matthew Henry Commentary
Verses 1-8 - In the court before the tabernacle, where the people attended, was a 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. grate of brass was let into the hollow of the altar, about the middl 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 fal through. This brazen altar was a type of Christ dying to make atonemen 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 Chris have borne the wrath of God, if it had not been supported by Divin power.
