Exodus 25:40

And look that thou make them after their pattern, which was showed thee in the mount. Moses had seen the picture, or model, and he was to have an exact copy made. The golden candlestick, which is here described in such detail, was to remind Israel of the high calling which the believers have in this world. And in the same way the Christians are never to lose sight of the fact that the Lord expects them to be the light of the world, that they should let their light shine before men in word and work.
