In several noticeable respects Hebrews differs from all the other Epistles of the New Testament. The name of the writer is omitted, there is no opening salutation, the ones to whom it was first specifically and locally sent are not mentioned. On the positive side we may note, that the typical teachings of the Old Testament are expounded here at greater length than elsewhere, the priesthood of Christ is opened up, fully, only in this Epistle, the warnings against apostasy are more frequent and more solemn, and the calls to steadfastness and perseverance are more emphatic and numerous than in any other New Testament book. All of these things are accounted for by the fleshly nationality of those addressed, and the circumstances they were then in. Unless we keep these features steadily in mind, not a little in this Epistle will necessarily remain obscure and dark.
