As to the external evidence for the book's early date, we must remember that the Epistle to the Hebrews and the Book of Revelation, though admittedly earlier, are of the same school, and, with the great Pauline.
The Epistle to the Hebrews is an epistolary treatise of uncertain date, on the Pauline model, and by a disciple of St Paul or at least a writer strongly influenced by him, though influenced also in no small degree by the Jewish school of Alexandria represented by Philo.
In St Paul we find the beginnings of explanation, indeed of two explanations, and in the Epistle to the Hebrews the whole sacrificial system is found to culminate in Christ, of whom all priests and sacrifices are symbols, so that they are abolished with the coming of the great reality.
His greatest work, his commentary on the epistle to the Hebrews (Brief an die Hebrl er erldutert durch Einleitung, Ubersetzung, and fortlaufenden Commentar, in three parts, 1828, 1836 and 1840) won the highest praise from men like De Wette and Fr.
