My NRSV version says something like this:
Job:38:21-23 writes:
"You know, for you were born then, And the number of your days is great! Have you entered the storehouses of the snow, Or have you seen the storehouses of the hail, Which I have reserved for the time of distress, For the day of war and battle?"
I interpret this not as a reference to storehouses of snow and hail, but to storehouses against "the time of distress," like bad weather or war.
