John Owen here analyses the text of Hebrews with care and provides a judicious interpretation which shows an impressive familiarity with a wide range of biblical scholarship. He also provides rich practical applications.
John Owen was an English theologian and "was without doubt not only the greatest theologian of the English Puritan movement but also one of the greatest European Reformed theologians of his day, and quite possibly possessed the finest theological mind that England ever produced" ("Owen, John", in Biographical Dictionary of Evangelicals, p. 494)
An avid John Owen reader should know that this project was started in 1668. There is development of theological distinctions even throughout the process of writing the Hebrews Commentary. With that being said, the most precious part of this commentary in my opinion is definitely his exegesis of Hebrews 1 in general.
