Exodus 25:37-40

Then you shall make the lamps [of the lampstand] seven in number [with one lamp at the top of the shaft]. The priests shall set up its seven lamps so that they will light the space in front of it. Its snuffers and their trays shall be of pure gold. It shall be made from a talent (50-80 lbs.) of pure gold, including all these utensils. See that you make them [exactly] after their pattern which was shown to you on the mountain. [Heb 8:5, 6]
