(31) And God saw all that He had made, and found it very good. And there was evening and there was morning, the sixth day.

Rabbi Judah bar Simon said: it does not say, ‘It was evening,’ but ‘And it was evening.’ Hence we derive that there was a time-system prior to this. Rabbi Abbahu said: This teaches us that God created worlds and destroyed them, saying, ‘This one pleases me; those did not please me.’ Rabbi Pinhas said, Rabbi Abbahu derives this from the verse, ‘And God saw all that He had made, and behold it was very good,’ as if to say, ‘This one pleases me, those others did not please me.’
