Numbers 17:4

4.And thou shalt lay them up in the tabernacle. The place itself had not a little to do with the effectual decision of the matter; because it was clearly manifested that God was the author of the miracle, and consequently that the priesthood proceeded from Him. For we have elsewhere said that the whole government of the Church so entirely depends upon His decree, that men are not permitted to interfere with it. Wherefore He set the ark of the covenant in opposition to the voices of the whole people, in order to testify that no further dispute was to be raised respecting the priest, whom He had appointed by His own declaration and authority. At the same time, it had the effect of consoling the people, and silencing their complaints that the rods of all the tribes were brought in common into the sanctuary before God; for, although a peculiar dignity was accorded to that of Aaron alone, still the people ceased not to be a priestly kingdom. Hence it follows, that the honorable privilege conferred on one family contributed to the public welfare of all; so far was it from being the case that their inferiority ought to have caused them pain or envy.
