Multiple worlds

Hi,

"It is written (Ecclesiastes), ‘He made all in its proper time.’… R’ Avahu said: We see from here that Gd created worlds and destroyed them, created worlds and destroyed them, until he created these and said, ‘This is good for me, those were not good for me.’

"R’ Pinchas said: R’ Avahu based himself on the verse, ‘And Gd saw all that He had created, and it was very good’ - This good for me, those were not good for me."

(Midrash, Bereishit Rabbah 9:2)

Have a great day,
Mordechai
