Exodus 27:1-3

“Now 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.

And you shall make its pails for removing its ashes, and its shovels, its basins, its forks, and its firepans; you shall make all its utensils of bronze.
