2 Pet 3:15-16 And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; 16 As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.
Where, in that Scripture, does it say the Paul wrote Hebrews? I believe that every one of Paul’s Epistles ends with his name as the author of it. And yet Hebrews does not.
