Spoiler alert, it never happened and was added 500 years later.

Then how was Jerome (who had access to better manuscripts than we have today) to be writing commentaries on it as if it were old news in the early 400s?

I thought the article is only referring to the detail of Jesus writing in the sand. Never questioned that he said “Let he who is without sin....”
Have to admit this detail about writing in the sand is not one I recall learning, or at least never focused on.

It’s a fine detail and very nice that people speculate on what was written.
