V.1-4 The candlestick gave the only light in the tabernacle. It was in the first room “the holy place.” God is light (1 John 1:5), Jesus was the light of the world (John 9:5) and the Holy Spirit is the oil (the power) which enables that light to shine. Seven lamps tell us that it was perfect. Let us see to it that the light of our life, what we say and do, is for the glory of the Lord alone. (Read Matt. 5:14-16). What a responsibility we have!
V.6-22 The Levites are to be prepared for the service of the Lord. Only water, not blood is used. (See John 13:6-10). The water is like the Word of God. Believers need the Word to keep clean (Eph. 5:25). Remember the priests were for the worship of God, but the Levites (this chapter) were for service. Verse 19 shows that the Levites were secondary to the priests. We believers are both, but worship must take first place. Read these verses slowly.
V.23-26 The mature and productive years of their life were to be devoted to the Lord’s service. After 50 years of age, they could go into the tabernacle, but not to do any work of service.
