Torah Temimah cites Megillah 9a.
An incident with King Ptolemy who gathered seventy-two elders and placed them in seventy-two separate houses without telling them why. He went to each and said: Write for me the Torah of Moses your teacher. The Holy One, blessed be He, placed counsel in the heart of each one, and they all arrived at the same decision and wrote for him: “God created in the beginning” (reversing the order).
