Exodus 30:1-3

¹And thou shalt make an altar to burn incense upon: of acacia wood shalt thou make it. ²A cubit shall be the length thereof, and a cubit the breadth thereof; foursquare shall it be; and two cubits shall be the height thereof: the horns thereof shall be of one piece with it. ³And thou shalt overlay it with pure gold, the top thereof, and the sides thereof round about, and the horns thereof; and thou shalt make unto it a crown of gold round about.
