Exodus 27:1-3

“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. Make 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. 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.
