Numbers 7-9…Tabernacle dedication offerings, the lighting of the lamps, and the Passover.
It was a time of joy and rejoicing, but in the midst of their sacrifices, we find a sin-offering in Numbers 7. So it is for us, that even when we do good, we are conscious that there is sin (Romans 7:21), and there should be repentance. In all approaches to God we must by faith look to Christ as the Sin-offering.
Aaron himself lit the lamps in Numbers 8, representing his Divine Master. God’s word is a light shining in a dark place (2 Peter 1:19). The church is dark without it, just as the tabernacle, which had no window, would have been without the lamps. The work of pastors/elders 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.
In Numbers 9, we see a very similar corporate gathering and time of consecration similar to our partaking of the Lord’s supper today. Instructions were given concerning those who were ceremonially unclean, when they were to eat the passover. Similar careful instructions are given in the New Testament. Those whose minds and consciences are persistent and unrepentant in sin, are unfit for communion with God, and cannot partake with comfort of the Lord’s supper, until they are cleansed by true repentance and faith (1 Corinthians 11:29).
