Exodus 25: 31 – 37: And thou shalt make a candlestick of pure gold: of beaten work shall the candlestick be made: his shaft, and his branches, his bowls, his knops, and his flowers, shall be of the same. And six branches shall come out of the sides of it; three branches of the candlestick out of the one side, and three branches of the candlestick out of the other side: Three bowls made like unto almonds, with a knop and a flower in one branch; and three bowls made like almonds in the other branch, with a knop and a flower: so in the six branches that come out of the candlestick. And in the candlestick shall be four bowls made like unto almonds, with their knops and their flowers. And there shall be a knop under two branches of the same, and a knop under two branches of the same, and a knop under two branches of the same, according to the six branches that proceed out of the candlestick. Their knops and their branches shall be of the same: all it shall be one beaten work of pure gold. And thou shalt make the seven lamps thereof: and they shall light the lamps thereof, that they may give light over against it.
The seven-branched candlestick or Menorah that Moses was instructed to make was representative of not just the seven church ages (Revelation 1: 20), but of the Bible that gives Light to the world (Psalm 119: 105: Thy word is a lamp unto my feet, and a light unto my path.). On each of the Menorah’s branches there was to be three cups (in the form of flowers), and each cup had buds and blossoms, whilst the central branch had four cups, each with their buds and blossoms.
Each branch therefore had nine decorations (three cups, three buds, and three blossoms), whilst the central branch had twelve decorations (four cups, four buds, and four blossoms). The grand total of cups, buds, and blossoms of the seven-branched Menorah was 66, equating to the 66 books of the Bible. If we take the total number of decorations for the three left-hand branches and the central branch (9+9+9+12), we get 39, representing the 39 books of the Old Testament. And when we take the total number of decorations for the three right-hand branches (9+9+9), we get 27, representing the 27 books of the New Testament.
