What does the Bible say about the role of the Levites?

In Numbers 8, the Levites are chosen by God to serve in the tabernacle, illustrating God's sovereign election among His people. They assist the priests in their sacred duties, showing that not all Israel is of Israel, as the Levites represent a distinct group chosen for holy service. This reflects the doctrine of election, where God selects a specific people for Himself for the purpose of worship and service. The act of gathering the assembly to witness the setting apart of the Levites also emphasizes that salvation and service are visible aspects of God's work among His covenant people.
