כי בו שבת, the word שבת when applied to G-d, cannot mean “He rested,” in the sense this term is commonly used, as we have it on the authority of Isaiah 40,28 that G-d never “grows faint or weary;” seeing that He did not have to exert Himself when creating the universe, why should He have been tired so that would have to “rest?” The word has to be understood as G-d having put a temporary stop to an activity. We find a similar term used when the regular descent on weekdays of the manna came to a halt after the Israelites had crossed the Jordan, (Joshua 5,12) before they commenced eating from the produce of the land of Canaan. Both events are reported there as having occurred on the same day. We also find the verb שבת used in the sense of an interruption Job 32,1 when Job’s friends interrupted their arguing with Job for three days out of their respect for his righteousness. An even better proof is Genesis 8,22, where G-d assures Noach after the deluge that the regular phenomenon of day and night following one another will never again be suspended, i.e. יום ולילה לא ישבתו, “day and night will occur without interruption.” Neither day nor night will take “a break from their routine.”

And now, they did not see the rain At the conclusion of his words, Elihu returns to chide Job’s three companions for not finding an answer. He therefore says, “And now, these three companions of yours, who should have answered you all these things that I said to you... did not see the rain” They are like stillborn babies, who did not see wisdom.
