As water had been the occasion for the punishment of Moses, God did not say that that which He had created on the second day of the creation "was good," for on that day He had created water, and that which brought about Moses' death was not good.
If the death doomed for Moses upon this occasion was a very severe punishment, entirely out of proportion to his offense, then still more so was the death destined for Aaron at the same time. For he had been guilty of no other offense than that of joining Moses at his transgression, and "who so joins a transgressor, is as bad as the transgressor himself." On this occasion, as usual, Aaron showed his absolute devotion and his faith in God's justice. He might have said, "I have not sinned; why am I to be punished?" but he conquered himself and put up no defense, wherefore Moses greatly praised him.
