Exodus 38:1-5

The altar of burned offerings he made of hard wood; a square altar, five cubits long, five cubits wide and three cubits high, And he put horns at its four angles made of the same, plating it all with brass; And brass was used for all the vessels of the altar, the baskets and the spades, the basins and the meat-hooks and the fire-trays; all the vessels he made of brass And he made a network of brass for the altar, under the frame round it, stretching half-way up; And four rings for the four angles of this network, to take the rods.
