The tithe from the people was given to the Levites (vv. 21, 26a), and the tithe of the tithe (v. 26b) from the Levites was given to Aaron the priest to be offered to God as a heave offering. This became God’s food, a portion of which was also the food of the priests. Thus, the Levites lived on the tithe from the people, and God and the priests lived on the tithe from the Levites.
God and His people, including the serving ones, were one large family. In this family God the Father as the source gave the good land to His children, who then had to work the land. Eventually, they reaped a harvest, which was to be enjoyed by both God and all the people. They were to bring a portion of the produce to the serving ones, and the serving ones were to offer a portion of what they received to God. In this way, God and His serving ones shared the tithes and lived together.
The good land is a type of the all-inclusive Christ (see note Deut. 8:71). God’s food is the riches of Christ, typified by the produce of the good land, and this produce comes through our labor. We need to labor on Christ and experience Christ. Then Christ will be the produce not only for our satisfaction but also for God’s satisfaction.
