Exodus 27:3-5

Amplified Bible

³ You shall make pots to remove its ashes, and shovels, basins [to catch the blood of the sacrificed animal], meat-forks, and firepans [to store live coals]. You shall make all its utensils of bronze. ⁴ Also make a grate for it, a network of bronze; and on the grid you are to make four bronze rings at its four corners. ⁵ And you shall put it under the ledge of the altar, so that the grid will extend halfway up the altar.
