Did Paul write the Epistle to the Hebrews?

The authorship of the Epistle to the Hebrews is an open question. The common scholarly opinion is that the author certainly wasn't Paul. Most modern Bible translations make no mention of the author, but some older ones such as the King James Version do: > Personally, I find it hard to believe that Paul would have written Heb 2:3-4. In his other letters, he always highlights himself as one of the apostles; here the writer has a very humble attitude and certainly doesn't count himself an apostle. > [**Hebrews 2:3-4 (KJV)**](http://www.biblegateway.com/passage/?search=Hebrews%202:3-4&version=KJV) > 3How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; > 4God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will? Was Paul the author of Hebrews? What supports Pauline authorship?
