Hebrews 13:25

From Textus Receptus

Timothy was dictated to by Paul. If you look at a King James Version, it states before chapter 1: "The Epistle of PAUL The Apostle To The Hebrews"

The very last words say: "Written to the Hebrews from Italy, by Timothy."

Just as in Philemon which ending with [Written from Rome to Philemon, by Onesimus] which suggests Onesimus is the author of Philemon, which nobody contends because it begins with "Paul and Timothy unto Philemon". As a gifted orator, Paul often orated epistles penned by another, as a lawyer orates and a secretary types.
