10. And the Lord said unto Moses. What God had prescribed concerning the censers, He now commands as to the rod, i.e., that it should be preserved as a monument for future ages; because men are forgetful and slow to consider His works, and not only so, but because they bury their memory as if of deliberate malice, he bids, therefore, and not without reproach, that this sign should be laid up in safety, saying, that this is done on account of their perverseness. At the same time, however, He commends His paternal love and pity, in that, whilst tie chastises their pride, He provides for their welfare. For, as they were given to rebellion, they would still have provoked His wrath by new murmurings. He says, then, that He anticipates them, and restrains their impetuous fury, lest they should die. Thus in humbling us, tie not only punishes our transgressions, but tie has regard to what is profitable for us, and proves that He cares for us.
