God is Tough on the Righteous

Although Nechunya ensured that others would have water,
even so, his son died of thirst, fulfilling the idea:

And around Him it storms [nisara] mightily.

This teaches that God is scrupulous with those around Him,
i.e., the righteous, even to the extent of a hairsbreadth [hasa’ara],
so that even minor transgressions elicit a severe punishment.
