John Wesley on Numbers 20:2

No water - Which having followed them through all their former journeys, began to fail them here, because they were now come near countries, where waters might be had by ordinary means, and therefore God would not use extraordinary, lest he should seem to prostitute the honour of miracles. This story, though like that, Exo 17:1 - 7, is different from it, as appears by divers circumstances. It is a great mercy, to have plenty of water; a mercy which if we found the want of, we should own the worth of.
