Exodus 25:8-11

And let them make me a sanctuary, that I may dwell among them. According to all that I show thee, the pattern of the tabernacle, and the pattern of all the furniture thereof, even so shall ye make it. And they shall make an ark of acacia wood: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof, and a cubit and a half the height thereof. And thou shalt overlay it with pure gold, within and without shalt thou overlay it, and shalt make upon it a crown of gold round about.
