"And the LORD spake unto Moses, saying, Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him. And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle." (v.5-7)
Here we see the tribe of Levi presented to the LORD as a sacrifice of service entirely to the sanctuary. They no longer are their own, but the Lord's property and shall work for the whole congregation.The Levites were to perform the most common and laborious duties. It was their business to take down, put up, and carry the tabernacle and its utensils; for it was the object of their peculiar care. In a word, they were the servants of the priests. This was an honor given to the Levites by God to serve Him.
Every congregation has it's Levites and could not function without them. The business of set-up, break down, clean-up, parking, security, etc. Carrying out all the laborious work that goes into preparing the church, before the doors even open. Have you ever noticed that those who do the work are usually joyful in their labor? Why is that? Because it's an honor to do so.
The Truth: "Therefore, "They are before the throne of God and serve Him day and night in His temple; and He who sits on the throne will shelter them with His presence." (Revelation 7:15)
