81 And the Lord said to Moses, 2 Say to Aaron, When you put the lights in their places, the seven lights will give light in front of the support. 3 And Aaron did so; he put the lights in their places so that they gave light in front of the support, as the Lord gave orders to Moses. 4 The support for the lights was of hammered gold work, from its base to its flowers it was of hammered work; from the design which the Lord had given to Moses, he made the support for the lights.

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.
