The author of Hebrews

“Greet all your leaders and all God’s people. Those from Italy send you their greetings. Grace be with you all.” Hebrews 13:24-25
Hebrews 13:25 may give us an indication as to who the author of Hebrews was. “Grace be with you” was Paul’s sign-off. It appears at the end of all the other epistles that he wrote: Rom. 16:20, 1 Cor. 16:23, 2 Cor. 13:14, Gal. 6:18, Eph. 6:24, Phil. 4:23, Col. 4:18, 1 Thess. 5:28, 2 Thess. 3:18, 1 Tim. 6:21, 2 Tim. 4:22, Tit. 3:15, Phm. 1:25. It is not used by any of the other New Testament writers (James, Peter, John).
We also know some other things about the author. He worked with Timothy (Heb. 13:23). Certainly the readers knew who he was (Heb. 13:19). We also know that Paul longed to minister to the Jews (Rom. 9:1-4, Rom. 11:13-14). But given the hatred of the non-believing Jews towards him wherever he went – they saw him as a traitor to their religion – it would make sense that if Paul did write a letter to his own people, he would not sign it by name. The writer of the book of Hebrews also shows mastery in Hebrew logic and a deep knowledge of the priesthood and temple service – something that would be expected from a Pharisee, as Paul was. In addition, Peter mentions that Paul did write to Jewish believers (2 Pet. 3:15).
Other suggestions as to the authorship of Hebrews have included Apollos, Barnabas, and Priscilla, but with little Scriptural backing to support these.
If you happen to disagree with me on this, I must apologise and say that I don’t want it to be a stumbling-block! Regardless of who the human writer was, the book of Hebrews is ultimately inspired by the Holy Spirit.
