Amongst the many chiddushim, novellae, he published, the Rogatchover included an explanation of a posuk, explaining why the verse in two places uses two different words to describe what seems to be the same thing.
(The Rogatchover)
[I could not hear which specific posuk]
Rabbi Shlomo Yosef Zevin, editor of Encyclopedia Talmudit, wrote the Rogatchover regarding this particular chiddush, "I saw one particular small and old book, by the name of the "Chumash", and there the pesukim (the verses) do indeed use the same word".
(Rabbi S.Y Zevin with grandchild)
The Rogatchover responded by first thanking Rabbi Zevin for the correction and then continued, "see Maimonides chapter... in this particular version of the text, you will see he quotes the verse as I did".
