Exodus 38:1-3

Revised Geneva Translation

38 Also, he made the Altar of the Burnt Offering of shittim wood. Its length was five cubits, its breadth five cubits (it was square); and it was three cubits high.

² And he made horns for it, on its four corners. Its horns were part of the same piece; and he overlaid it with copper.

³ Also, he made all the instruments of the altar: the pans, the shovels, the basins, the fleshhooks, and the firepans. He made all its instruments of copper.
