Exodus 27:1-8

¹“And you shall make the altar [for burnt offerings] of acacia wood, five cubits long and five cubits wide; the altar shall be square, and its height shall be three cubits. ²Make horns (horn-shaped projections) for it on its four corners; the horns shall be of one piece with it, and you shall overlay it with bronze. ³You 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. ⁴Also make a grate for it, a network of bronze; and on the grid you are to make four bronze rings at its four corners. ⁵And you shall put it under the ledge of the altar, so that the grid will extend halfway up the altar. ⁶You shall make [carrying] poles for the altar, poles of acacia wood, overlaid with bronze. ⁷The poles shall be inserted through the rings on the two sides of the altar so that it may be carried. [Num 4:14, 15] ⁸You are to make the altar hollow with planks; as you were shown on the mountain [of Sinai], so shall it be made.
