• The commentaries out of copyright were imported from SermonIndex’s modules, CrossWire’s SWORD modules, Bible Hub (Poole, Haydock, Hodge, Wesley, and the People’s New Testament), and the CC0 edition of the Catena Aurea in Newman’s translation. What we changed in all the commentaries: references to Bible verses are links, which in print they could not be. In those from SermonIndex’s modules, also: Greek words the modules ran together spaced apart again (tens of thousands in each of Meyer, the ICC, Lange, Alford, the Expositor’s Greek Testament, and Bengel); Hebrew the modules had turned into Greek letters put back into Hebrew (in Lange, the Cambridge Bible, Benson, Ellicott, and Keil and Delitzsch), with its vowel points only where the word is one of its verse’s own; a passage of Scripture reprinted before the comment on it left out, since the verses are on the page (most often in Matthew Henry).
