Not everybody is called to be a priest or a leader. Some are called to be helpers, such as the Levites. The gift of helps (1 Cor. 12:28) is important in God’s work and must never be despised. God considered the Levites as His gift to Aaron (v. 19). We should be thankful for those God gives to help us in our work.
Substitutes. The Levites were first of all given to the Lord as substitutes for all the firstborn in Israel (vv. 16–18; 3:11–13). The firstborn belonged to God, but He allowed them to be redeemed (Exod. 13:1, 11–13). You have your work to do for Christ, but don’t forget those who represent you as they serve the Lord in different places.
Servants. The Levites were given to Aaron as workers (vv. 11, 19). They could not do all that the priests did, but they had their tasks and were expected to fulfill them faithfully.
Sacrifices. They were presented to God as “living sacrifices,” wave offerings to the Lord (vv. 11, 13, 15, 21). No matter what work you do for the Lord, it should be like offering up a sacrifice of worship to Him (Phil. 4:10–20).
