What does the Bible say about the Levites' role in Numbers 4?

In Numbers 4, God commands Moses and Aaron to take a census of the Levites, specifically the sons of Kohath, Gershon, and Merari, who were responsible for the service of the tabernacle. The Levites were chosen instead of the firstborn sons of Israel to handle the most holy things, signifying their important role in offering service to God. This chapter underscores the division of labor among the Levites, as they were tasked with various responsibilities, from carrying heavy burdens to maintaining the furnishings of the tabernacle, reflecting their vital role in the worship and ministry of Israel.
