See the Google Sheet containing a complete list of epistrophes of 3+ pesukim in TanachGoogle Sheet containing a complete list of epistrophes of 3+ pesukim in Tanach that I posted. The large majority of these 89 occurrences are not within sections of songs/poetry. Some of these have already been mentioned earlier in this discussion.
I have noted there in bold/red font where the 3+ pasuk criteria is enabled or extended by the final word in a pasuk having a common root or a common spelling as opposed to an exact letter/vowel match.
As a bonus and just for fun, I added a new tab to the spreadsheet called ע"פ גמטריא that contains the only two occurrences in Tanach where three consecutive pesukim end with words having the same gematria even though not all the three actual words are the same:
- gematria = 215: יחזקאל:א:כד-כו (כנפיהן, כנפיהן, מלמעלה)
- gematria = 61: תהלים:פו:א-ג (אני, אליך, היום)
For your interest, also see this related question which deals with consecutive pesukim which match on their final three or more words.
