Question:

Who wrote the book of Hebrews?

Some think that Barnabas wrote it.  Some say Timothy.  Some say Paul. Hebrews 13:23 and 2 Peter 3:15 may be good clues that Paul wrote it. We know that the Lord really wrote this book (2 Timothy 3:16, 17).

The fact that the human writer is not mentioned shows that the attention is be on the Lord and the Holy Spirit who guided that person to write it. (Edited).
