³ And thou shalt make its pots to cleanse it of the fat, its shovels, and its bowls, and its forks, and its firepans; for all the utensils thereof thou shalt employ copper.

⁴ And thou shalt make for it a grating of network of copper; and on the net shalt thou make four copper rings at its four corners;

⁵ and thou shalt put it under the ledge of the altar beneath, and the net shall be to the very middle of the altar.
