After six chapters detailing the importance of the Levites work at the tabernacle, this chapter shows the support and contributions (six wagon loads) of all the tribes to that work. For 12 successive days, each tribe gives a contribution that would enable the Levites and priests to begin carrying out the regular worship at the consecrated tabernacle. This was a show of equal consecration of the whole nation, and each tribe in particular. Although the priests and Levites only come from one tribe, the tabernacle was the LORD’s, and he was not the God of one tribe alone.
A New Testament corollary is found in Romans 12:4-8:
“For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another. Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith;if service, in our serving; the one who teaches, in his teaching;the one who exhorts, in his exhortation; the one who contributes, in generosity; the one who leads, with zeal; the one who does acts of mercy, with cheerfulness.”
