There is this very useful commentary named “Lectionary Study” which has decent comments on verses plus a syntax commentary, which i have not found elsewhere at all. Exegetical study notes on the Greek New Testament
Thank you for the suggestion. Given the intentional lack of copyright, I’ll definitely take a look. Do you know anything about the author? Without some of that information, I’d want to read most/all of it before trying to add it because I wouldn’t have sufficient reason to trust its reliability enough to republish it (we try to be very careful about what we put on Relight and make sure it’s in accordance with the reformed confessions and catechisms).
Sorry for the delayed reply.
