Benedictions, or closing blessings, were an important part of letters, speeches, and sermons. The author of Hebrews includes many of the book’s main themes in his benediction.
The image of our Lord Jesus as the great Shepherd of the sheep (see Psalm 23) shows God's care and protection for his people (see also John 10:11–18; 1 Peter 2:25) and connects it to an eternal covenant.
