You shall make the altar of acacia wood, five cubits long and five cubits wide; the altar shall be square, and it shall be three cubits high. You shall make horns for it on its four corners; its horns shall be of one piece with it, and you shall overlay it with bronze. You shall make pots for it to receive its ashes, and shovels and basins and forks and firepans; you shall make all its utensils of bronze. You shall also make for it a grating, a network of bronze; and on the net you shall make four bronze rings at its four corners. You shall set it under the ledge of the altar so that the net shall extend halfway down the altar. You shall make poles for the altar, poles of acacia wood, and overlay them with bronze; the poles shall be put through the rings, so that the poles shall be on the two sides of the altar when it is carried. You shall make it hollow, with boards. They shall be made just as you were shown on the mountain.
