Numbers 8:1-4

And Jehovah spake unto Moses, saying, Speak unto Aaron, and say unto him, When thou lightest the lamps, the seven lamps shall give light in front of the candlestick. And Aaron did so; he lighted the lamps thereof so as to give light in front of the candlestick, as Jehovah commanded Moses. And this was the work of the candlestick, beaten work of gold; unto the base thereof, and unto the flowers thereof, it was beaten work: according unto the pattern which Jehovah had showed Moses, so he made the candlestick.
