Gd's conversations with Moshe

Hi,

"[It is written,] 'And Gd spoke [וידבר] to Moshe,' 'And Gd said [ויאמר] to Moshe,' and 'And Moshe said [ויאמר] to Gd,' 'And Moshe spoke [וידבר] to Gd.'

"This may be compared to a cave which is located at the shore. The sea rises and fills it, and then the sea does not leave it. From then on, the sea gives water to the cave, and the cave to the sea."

(Midrash, Shemot Rabbah 45:3)

Have a great day,
Mordechai
