Exodus 27:1-3

“And you shall make the altar of acacia wood, five cubits long and five cubits wide; the altar shall be square, and its height shall be three cubits. You shall make its horns on its four corners; its horns shall be of one piece with it, and you shall overlay it with bronze. You shall make its pails for removing its ashes, and its shovels and its basins and its forks and its firepans; you shall make all its utensils of bronze.
