The sons of Levi where types of Christ's brethren

The Kohathites, Gershonites, and Merarites, all sons of Levi, to whom was appointed the duty of carrying the tabernacle and its contents when the camp moved forward (Num. 4.), were types of Christ’s brethren in their present wilderness march; and the holy things which were carried find their counterpart in the Holy Scriptures and all that they teach. It was at the peril of these Levites to evade the “service” and “burden” imposed upon them (ver. 49); no less can be said of the sons of God and their corresponding obligation. It is, doubtless, from this point of view that the apostle describes “the church of the living God” as “the pillar and ground of the truth” (1 Tim. 3:15).
