81 And the Lord spoke to Moses, saying: 2 "Speak to Aaron, and say to him, 'When you arrange the lamps, the seven lamps shall give light in front of the lampstand.' " 3 And Aaron did so; he arranged the lamps to face toward the front of the lampstand, as the Lord commanded Moses. 4 Now this workmanship of the lampstand was hammered gold; from its shaft to its flowers it was hammered work. According to the pattern which the Lord had shown Moses, so he made the lampstand.

Aaron himself lighted the lamps, thus representing his Divine Master. The Scripture is a light shining in a dark place, 2 Peter 1:19. A dark place even the church would be without it; as the tabernacle, which had no window, would have been without the lamps. The work of ministers is to light these lamps, by expounding and applying the word of God. Jesus Christ is the only Light of our dark, sinful world; and by his atonement, by his word and the Holy Spirit, he diffuses light around.
