9. I John--So "I Daniel" (Da 7:28; 9:2; 10:2). One of the many features of resemblance between the Old Testament and the New Testament apocalyptic seers. No other Scripture writer uses the phrase.
      also--as well as being an apostle. The oldest manuscripts omit "also." In his Gospel and Epistles he makes no mention of his name, though describing himself as "the disciple whom Jesus loved." Here, with similar humility, though naming himself, he does not mention his apostleship.
      companion--Greek, "fellow partaker in the tribulation." Tribulation is the necessary precursor of the kingdom," therefore "the" is prefixed. This must be borne with "patient endurance." The oldest manuscripts omit "in the" before "kingdom." All three are inseparable: the tribulation, kingdom and endurance.
      patience--Translate, "endurance." "Persevering, enduring continuance" (Ac 14:22); "the queen of the graces (virtues)" [CHRYSOSTOM].
      of, &c.--The oldest manuscripts read "IN Jesus," or "Jesus Christ." It is IN Him that believers have the right to the kingdom, and the spiritual strength to enable them to endure patiently for it.
      was--Greek, "came to be."
      in . . . Patmos--now Patmo or Palmosa. See Introduction on this island, and John's exile to it under Domitian, from which he was released under Nerva. Restricted to a small spot on earth, he is permitted to penetrate the wide realms of heaven and its secrets. Thus John drank of Christ's cup, and was baptized with His baptism (Mt 20:22).
      for--Greek, "for the sake of," "on account of"; so, "because of the word of God and . . . testimony." Two oldest manuscripts omit the second "for"; thus "the Word of God" and "testimony of Jesus" are the more closely joined. Two oldest manuscripts omit "Christ." The Apocalypse has been always appreciated most by the Church in adversity. Thus the Asiatic Church from the flourishing times of Constantine less estimated it. The African Church being more exposed to the cross always made much of it [BENGEL].
