Exodus 38:1-8

1And he made the altar of burnt offering of shittim wood: five cubits was the length of it, and five cubits the breadth of it; it was foursquare; and its height was three cubits. 2And he made its horns on its four corners; its horns were of the same: and he overlaid it with brass. 3And he made all the vessels of the altar, the pots, and the shovels, and the basins, and the fleshhooks, and the firepans: all the vessels of it he made of brass. 4And he made for the altar a brasen grate of network under its rim beneath to the midst of it. 5And he cast four rings for the four ends of the grate of brass, to be places for the staffs. 6And he made the staffs of shittim wood, and overlaid them with brass. 7And he put the staffs into the rings on the sides of the altar, to bear it with; he made the altar hollow with boards. 8And he made the laver of brass, and the foot of it of brass, of the lookingglasses of serving women, who served at the door of the tabernacle of the congregation.12
