Exodus 38:1-3

American Standard Version

38 And he made the altar of burnt-offering of acacia wood: five cubits was the length thereof, and five cubits the breadth thereof, foursquare; and three cubits the height thereof. ² And he made the horns thereof upon the four corners of it; the horns thereof were of one piece with it: and he overlaid it with brass. ³ And he made all the vessels of the altar, the pots, and the shovels, and the basins, the flesh-hooks, and the firepans: all the vessels thereof made he of brass.
